OpenMP on FreeBSD is a bit of PITA:
- base/ system on Clang archs doesn't provide libomp or libgomp
- libomp from LLVM openmp is guaranteed to be available only on amd64
- USES=compiler:openmp doesn't know about LLVM openmp (bug 210337)

archivers/pxz supports non-OpenMP by removing -fopenmp from CFLAGS.

Maybe. /usr/bin/xz --threads=NUM is supported on all FreeBSD releases.
