Repeating the test on a massively multicore system, it fails at stage2 with an
in-tree 0.14 because -lisl cannot be found at gcc/configure time. Hence,
HAVE_ISL_SCHED_CONSTRAINTS_COMPUTE_SCHEDULE is false and one gets later an
error because a 0.12.2 function is not available with ISL 0.14.
However, running the configure test case manually - or building with fewer
cores - works. As does removing "gcc" after the failure such that isl/ is
available. Thus, it looks like a dependency problem.
It seems to be fixed by the attached patch.
OK for the trunk?

* Makefile.def: Make more dependent on mpfr, mpc and isl.
* Makefile.in: Regenerate.
This is OK for the trunk.
