[Buildroot] [PATCH v3 1/2] package/lua-lunix: fix build with recent gcc

[Yann E. MORIN]

François, All,

The commit title is wrong: as I explained in the upstream PR, the
problem is not with "recent gcc".

The header of concern is from the C library, so it is missign from
recent glibc versions.

And eventually, the sysctl syscall is missing in recent kernel versions.
Nothing to do with recent gcc versions.
