iproute2: support eBFP/XDP object file loading, simplify linking libelf Add build and runtime dependencies on libelf, allowing tc and ip-full to load BPF and XDP object files respectively. Define package 'tc' as a singleton package variant, which can be used to enable additional functionality limited only to tc. Also set ip-tiny as the default 'ip' variant. Preserve optionality of libelf by having configuration script follow the HAVE_ELF environment variable, used similarly to the HAVE_MNL variable.

iproute2: update to 5.11.0 The latest iproute2 version brings various improvements and fixes: https://git.kernel.org/pub/scm/network/iproute2/iproute2.git/log/?qt=range&q=v5.10.0..v5.11.0 In particular, ip and tc now use libbpf as the standard way to load BPF programs, rather than the old, limited custom loader. This allows more consistent and featureful BPF program handling e.g. support for global initialized variables. Also fix a longstanding problem with iproute2 builds where unneeded DSO dependencies are added to most utilities, bloating their installation footprint. From research and testing, explicitly using a "--as-needed" linker flag avoids the issue. Update accordingly and drop extra package dependencies from Makefile. Additional build and packaging updates include: - install missing development header to iproute2/bpf_elf.h - propagate OpenWrt verbose flag during build - update and refresh patches Compile and run tested: QEMU/malta-mips32be on kernels 5.4 & 5.10. All iproute2 packages were built and installed to the test image. Some regression testing using ip-full and tc was successfully performed to exercise several kmods, tc modules, and simple BPF programs.
