This fixes the download of the kernel 5.15 for the bpf-headers when
kernel 6.1 is build for the target.
Even if kernel 6.1 was selected for the target we still use kernel 5.15
for the bpf-headers. The download script tried to download the 5.15
kernel from the 6.x directory on kernel,org and this failed. Define
PKG_SOURCE_URL based on PKG_PATCHVER and not KERNEL_BASE like done in
kernel.mk.
Without this change it tries to download the kernel from this URL:
ttps://cdn.kernel.org/pub/linux/kernel/v6.x/linux-5.15.129.tar.xz

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.

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.

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

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

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
