sim: bfin: skip .c/.S tests if no compiler is available

Similar to logic in the cris exp, attempt a simple compile and if it fails
(presumably due to the compiler being broken), skip all the related tests.
Fortunately, most tests (~600 out of ~800) are pure assembly, so people should
still get pretty good coverage.
