[PATCH bpf-next v1 00/19] selftests/bpf: Improve libc portability / musl support (part 1)

[Tony Ambardar <tony.ambardar@gmail.com>]

Hello all,

This series includes the bulk of libc-related compile fixes accumulated to
support systems using musl, with smaller numbers to follow. These patches
are simple and straightforward, and the series has been tested with the
kernel-patches/bpf CI and locally using mips64el-gcc/musl-libc and QEMU
with an OpenWrt rootfs.

The patches address a few general categories of libc portability issues:

 - missing, redundant or incorrect include headers
 - disabled GNU header extensions (i.e. missing #define _GNU_SOURCE)
 - issues with types and casting

Feedback and suggestions for improvement are welcome!

Thanks,
Tony
