  There were no objections raised to the previous version of this change
and it only affects tile and (I believe) microblaze, so I tweaked it
slightly to use "#if" rather than "#ifdef" and pushed it.

	* math/test-fenv-preserve.c [FE_ALL_EXCEPT == 0] (do_test):
	Make the test a no-op if there are no exceptions defined.

This fixes a testsuite failure for tile (and possibly microblaze).
