9f67ed5460 bpf-headers: drop HOST_LOADLIBES
HOST_LOADLIBES was renamed to KBUILD_HOSTLDLIBS in kernel 4.19. As the
oldest kernel version we support is 5.10, cleanup HOST_LOADLIBES use.

4d904524ef kernel: bpf-headers: fix build error when testing kernel is used
Now that we have separate files for each kernel version,
only the version/hash for the target kernel are available.
This cause a missing hash error (and wrong kernel version) for
bpf-headers when a testing kernel version is used for the current target.

Fix this error by manually including the kernel version/hash file for the
specific kernel version requested.

8c1d5129ee bpf-headers: fix build error from within the SDK
The SDK does not ship the generic platform files. Use relative path for
GENERIC_PLATFORM_DIR to make it work. This points it at the files from
the feed directory instead of the base SDK path

8f355becdf bpf-headers: switch to mips64 for 64 bit targets
BTF pointer data has a different size on 32 vs 64 bit targets,
and while the generated eBPF code works, the BTF data fails to validate
on mismatch

da668eb03b bpf-headers: unset PKG_CONFIG_PATH
This fixes an issue where the kernel would pick up an incompatible target
libyaml for building host tools

a537d06c72 bpf-headers: add a package with kernel headers for ebpf
In order to genererate suitable kernel headers, a 5.10 kernel tree is
prepared with a default config for mips. The arch is forced to mips in
order to avoid issues with inline asm on various architectures in a way
that doesn't involve relying on the host toolchain/headers.
It also has the advantage of supporting both endian types
