[PATCH] Fix test-fenv

[Jakub Jelinek]

Hi!

Even other parts of test-fenv already ignore inexact exceptions when raising
overflow/underflow, so we should disable it in the feexcp_mask_test as well.
Makes test-fenv pass all tests on sparc64...

	* math/test-fenv.c (feexcp_mask_test): If enabling all exceptions
	and disabling underflow or overflow, disable inexact as well.
