Felix Fietkau 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

Felix Fietkau 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

Felix Fietkau 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
