The port was already removed.

No but...
- fixing USES=compiler is a separate task for someone interested
- requires testing consumers which is time-consuming
- aarch64, armv6, armv7 use Clang but don't support OpenMP yet
- i386 is partially broken due to missing libatomic i.e.,
  #pragma omp atomic is not usable with Clang
- USES=fortran consumers may use OpenMP but mixing OpenMP
  implementations leads to undefined behavior
