These two patch enable the use of "vmtest.sh" for cross-compile arm64 on x86_64 host.
This is essential for utilizing BPF on Android (arm64),
as the compilation server is running on Ubuntu (x86).
Following previous guidance from V1, the two changes are as follow:
V2:
- patch 2:
- [1/2] In Makefile, use $(SRCARCH) to get target arch's uapi.
Therefore, there is no longer a need to compile "make headers_install".
- [2/2] Regard "LDLIBS += -lzstd" as a separate patch for static compile.

- patch 2:
- [1/2] Update "vmtest.sh" for cross-compile arm64 on x86_64 host.
- [2/2] Fix cross-compile issue for some files and a static compile issue for "-lzstd"
Lin Yikai (2):
selftests/bpf: Enable vmtest for cross-compile arm64 on x86_64 host,
and fix some related issues.
selftests/bpf: fix static cross-compile error for liblstd.a linking.
