Aren't there any buildbots which perform 3-stage bootstraps with file
comparisons? Wouldn't it be simpler to just add openmp to the projects
sources on such a buildbot and adjust the test suite run there to
include libomp? That approach would insure that libomp is being built
with the same compiler compiler for a given revision.
