Patch the target triple for Rust with glibc to include hard floating
point support.
The GNU target triple used elsewhere does not include hard float support,
instead `-mfloat-abi=hard` is passed separately. For Rust it must be
included in the target triple. This was already being done for musl,
this commit adds the same patching for glibc.
Without this patch Rust compilation fails with an error like this
(abbreviated to fit the line length):
ld: error: libstd.so uses VFP register arguments, ... does not
ld: failed to merge target specific data of file ...

Using sccache makes recompilation of rustc and Rust packages faster.
This also makes the rust package visible in menuconfig, in order for the
sccache options to be accessible.

This allows cargo to use make's jobserver when building packages, by
marking the cargo command as recursive (with the + prefix[1]) and
setting MAKEFLAGS.
This also:
* Give cargo/x.py the build directory instead of having to change the
current directory (and opening subshells)
* Set PKG_BUILD_PARALLEL/HOST_BUILD_PARALLEL for Rust packages to enable
the use of make's jobserver

This consolidates all environment variables for cargo into:
* CARGO_HOST_CONFIG_VARS / CARGO_PKG_CONFIG_VARS
These contain all cargo-specific environment variables, i.e. without
"common" variables like CC.
* CARGO_HOST_VARS / CARGO_PKG_VARS (renamed from CARGO_VARS)
These contain all environment variables to be passed to cargo.
This also:
* Set the CARGO_BUILD_TARGET environment variable instead of using the
--target command-line option
* Update Python include files to use CARGO_HOST_CONFIG_VARS /
CARGO_PKG_CONFIG_VARS

As CARGO_HOME mainly functions as a download and source cache[1], moving
it into $(DL_DIR) allows it to persist and be reused between different
buildroots/sdks (when DL_DIR is set to a custom/external location).

This also:
* Modify the "release" profile in place of adding the "stripped" profile
Only the profile for target is modified; there are no file size
constraints for host.
* For host, build with the "release" profile
* For target, build with either the "dev" or "release" profile based on
CONFIG_DEBUG
There is no environment variable to specify the "strip" option, but
enabling this option is not necessary as the build system will already
strip binaries based on CONFIG_NO_STRIP / CONFIG_USE_STRIP /
CONFIG_USE_SSTRIP.

This allows rustc/cargo/etc to be called without having to set PATH, as
$(STAGING_DIR)/host/bin is already in PATH.
This also fixes CARGO_HOME not being set during Host/Configure and
Host/Compile.

* Compress dist archives with gzip instead of xz; gzip is faster to
compress and decompress
* Use a for loop instead of calling find to extract archives
* Use libdeflate's gzip to decompress instead of gzip
* Limit search for install scripts to top level of extracted archives
This also runs the install scripts with bash instead of sh, in
accordance with the shebang lines inside the scripts.

In order to use $(RUSTC_TARGET_ARCH) in HOST_BUILD_DIR, the line to
include rust-values.mk in the Rust makefile was moved in
f489e019ac, causing it to be included
before package.mk is included.
This had the side effect of preventing "-lssp_nonshared" from being
added to RUSTC_LDFLAGS, because PKG_SSP is indirectly set by package.mk
(package.mk includes hardening.mk, hardening.mk sets PKG_SSP).
There is a deeper issue; it is the Rust package's PKG_SSP value that
causes RUSTC_LDFLAGS to be set and written to the Cargo config file. For
packages that use Rust to build, their PKG_SSP value does not affect the
linker flag.
This sets rustflags with the RUSTFLAGS environment variable, instead of
writing the value to the Cargo config file, allowing PKG_SSP from the
package being built to be used and for the package being built to modify
the rustflags used.
This also:
* Fix "-lssp_nonshared" being added to TARGET_CFLAGS instead of
RUSTC_LDFLAGS, when CONFIG_PKG_CC_STACKPROTECTOR_STRONG is set.
* Remove the use of $(RUSTC_TARGET_ARCH) in HOST_BUILD_DIR and move the
include line for rust-values.mk back to after package.mk.
Since the host build directory was moved under the target build
directory in efdbac38dc, it is no longer
necessary to separate build directories with RUSTC_TARGET_ARCH;
$(BUILD_DIR) already separates build directories by target.
* Add BUILDONLY:=1, as the Rust package does not build a target package.
* Install the Cargo config file as "config.toml" instead of "config", as
this is the preferred form[1].
* Rename RUST_CFLAGS to RUSTC_CFLAGS and CONFIG_HOST_SUFFIX to
RUSTC_HOST_SUFFIX, for consistency.
* Allow CARGO_VARS to be set before rust-values.mk is included.

Fixes the commit 105fa3920e which was intended to make rust/host build
on aarch64 darwin working again. However, the fix contains a mistake
because it sets RUSTC_TARGET_ARCH instead of RUSTC_HOST_ARCH. Thus, the
fix doesn't work.
This properly sets the correct variable RUSTC_HOST_ARCH.

rust/host failed to compile on macOS running on Apple Silicon M1 Pro
because the host target triple is autogenerated to be
'arm64-unknown-linux-'. Rust doesn't have such a target triple, thus the
build failes because there are no pre-built artifacts for bootstrapping.
Fix this by setting RUSTC_HOST_ARCH to 'aarch64-apple-darwin' in case
our host is HOST_ARCH=arm64 and HOST_OS=darwin.

When user runs `make clean` command, everything in `$(STAGING_DIR)`
(where we installed rust) will be removed, but `$(BUILD_DIR_HOST)`
(where we compiled rust and stored build stage) is untouched.
So when user starts a new build after that, OpenWrt buildroot will
still consider `rust` is installed already, resulting the build error
"cargo: command not found".
Fix this by moving to target build dir as well.

While the compiled binaries are intended to run on the host system, the
rust/host package does include the target matching the configured
OpenWrt target.
If using (for example) ./scripts/env to switch between different
OpenWrt configurations, this will cause issues if the different
configuration is for a different target. In such case there will be a
mismatch between the available Rust target and OpenWrt target and the
following error will be printed:
> error[E0463]: can't find crate for `core`
> note: the `XXX` target may not be installed
This fix will add the RUSTC_TARGET_ARCH as HOST_BUILD_DIR and CARGO_HOME
suffix, such that rust/host will be compiled in case an OpenWrt
configuration change causes the RUSTC_TARGET_ARCH to change.
