Fix OptionalObsoleteFiles copy/paste mistake from r345236, which connected libomp to the build. The comparison should not have been against ${MK_OPENSSH}, but against ${MK_OPENMP}, obviously. MFC r347979: To avoid unnecessarily modifying ports, add a -lgomp symlink, since GCC does not ship a -lomp symlink. Also update OptionalObsoleteFiles for this, and add 32-bit variants while here.
