yes.
this has not much to do with the libc though.
openmp uses pthreads, pthreads uses clone and
clone is implemented by the os in some way.
whether things are parallel is not in the hands
of the libc and the logic is not target dependent,
the libc works the same way on x86_64 as on riscv.
there can be target specific synchronization bugs
in the libc, but those are just bugs.
