Because the first stage for building target Go is actually a host build,
the default platform options (GO386, GOARM, etc.) are detected from the
host. These values are written to a source file and kept when building
the second stage.
This modifies this source file to set the appropriate values for the
target platform, and reset values for other platforms to their
cross-compiling / most compatible defaults.

The variable is a list of shell variables; the new name is more in-line
with other parts the build system (CONFIGURE_VARS, MAKE_VARS, etc.).
GoPackage/Environment is kept (for now) in case other feeds are using
it.

The default bootstrap Go (Go 1.4) can only be compiled on a limited
number of platforms compared to newer versions of Go.
This adds a config option to use an external bootstrap Go, e.g.
installed through the build system's package manager or downloaded from
golang.org.

* Move more environment variables into GoPackage/Environment
* Split GoPackage/Environment into target and build sections
* Do not set GOROOT_FINAL for Go packages (setting it should only affect
the Go compiler and not Go packages)
* Set CGO_LDFLAGS to $(TARGET_LDFLAGS)
* Move GO_TARGET_* variables from golang-values.mk, and GO_VERSION_*
variables from golang-version.mk, into golang/Makefile
This also updates runc, containerd, and docker-ce to reflect the changes
in GoPackage/Environment.

* Set GOENV=off when building Go compiler and packages, to ignore user's
environment configuration file
* Set GOCACHE when building host Go
* Unset GOTMPDIR, to use the buildroot temp directory instead of temp
directories in build_dir

The ASLR PIE option was changed to a tristate option
(openwrt/openwrt@19cbac7d26). This updates
the Go compiler package and golang-package.mk to account for this
change.
This also adds warning messages for when the user has selected PIE but
Go does not have PIE support for the chosen target.

This adds support to compile host and target Go as position-independent
executables.
Host Go will have PIE enabled if Go supports PIE on the host platform.
Target Go will have PIE enabled if Go supports PIE on the target
platform and CONFIG_PKG_ASLR_PIE is selected.
Go 1.13 supports PIE for x86 and arm targets; mips support is in
progress[1].

Go 1.11 added softfloat support for 64-bit MIPS systems[1], so this also
adds builds for mips64 and mips64el.

This also changes the bootstrap source URL to the official GitHub
mirror, to make building easier for places where Google sites aren't
accessible. Fixes#6326.

From golang.org:
The Go programming language is an open source project to make
programmers more productive.
This commit consists of two "parts":
* golang/host: Main Go compiler for host (installed to
STAGING_DIR_HOST/lib/go-cross), used to cross-compile Go programs to
be packaged.
* golang (and golang-src/golang-doc): Main Go compiler for on-target
development. These packages are quite large, but I would expect only
developers to install these.
