but I think that the whole test now belongs in the GCC subdirectory, not
in the toplevel (it was anyway a hack for the sake of disabling Fortran).
Moving it is not really a good thing anyways as you are able to configure
and then do a "make -j3" and it is hard to figure out why the build fail
because you don't have the correct version of GMP/MPRF.
Maintainability first. If something fails with parallel make, and is
reproducible with plain "make" (i.e. doesn't screw up the build
directory), I don't see a reason not to move it. You'd do "make" anyway
to check if a dependency is missing, wouldn't you?
