[PATCH bpf-next v1 0/6] Change bpftool, libbpf, selftests to force GNU89 mode

[Kumar Kartikeya Dwivedi <memxor@gmail.com>]

Fix any remaining instances that fail the build in this mode.  For selftests, we
also need to separate CXXFLAGS from CFLAGS, since adding it to CFLAGS simply
would generate a warning when used with g++.

This also cherry-picks Andrii's patch to fix the instance in libbpf. Also tested
introducing new invalid usage of C99 features.
