[PATCH 0/9] tools/nolibc: fix build issues on aarch64 after unistd cleanup

[Willy Tarreau]

Hi Paul,

as per the recent discussion with Mark, I've updated the nolibc header to
reflect latest upstream which is needed to build on arm64, and I performed
the few cleanups that Mark rightfully suggested.

The following patches were taken from the upstream code and this time I
carefully copied the original commit IDs in hope not to miss such fixes
anymore in the future.

I've build-tested these on x86_64, i586, arm(v5 & v7), arm64, mips and
mipsel, using compilers ranging from gcc 3.4 to gcc 9.3 so I think we're
good for these archs now.

Just let me know if you prefer a pull request, as I can do that as well.

Thanks!
Willy
