The target libraries (libfortran, libstdc++, libgomp, etc.) are built
after all of the
compiler languages are built -- all stages.  libgomp currently is not designed
to be run in the build tree without the extra flags used by the testsuite.

You can test -ftree-parallelize-loops building GCC with an installed version
of GCC, but not as a three-stage bootstrap.
