And just to clarify, the rust libc crate supports different libc targets and
exposes mkostemp among others (all?) for both, the GNU libc a musl libc
targets.

So using that method might be indeed the best option for now and should not
hinder any static builds, as if not with glibc then we highly probably do
them with musl.
