Subject: gcc: Gnu OpenMP support depends on threading

Instead of checking if thread support is enabled during the build, move
the check to kconfig-time. Since if threading support is not availble,
libgomp should not be available either.

       The default is 'N'. Say 'Y' if you need it, and report success/failure.
