Subject: [PATCH bpf-next v2 2/2] selftests/bpf: fix static cross-compile error for liblstd.a linking.
Regard "LDLIBS += -lzstd" as a separate patch for static compile.
To fix static cross-compile error like this:
$LDLIBS=-static LDFLAGS=--sysroot=/aarch64-linux-gnu/libc ./vmtest.sh -s -- ./test_progs
/aarch64-linux-gnu/bin/ld: aarch64-linux-gnu/libc/usr/lib/libelf.a(elf_compress.o): in function `__libelf_compress':
(.text+0xec): undefined reference to `ZSTD_createCCtx'
/aarch64-linux-gnu/bin/ld: (.text+0xf0): undefined reference to `ZSTD_createCCtx'
...
