libgomp, testsuite: Do not call nonstandard functions

Browse source 
The following functions are not standard, and not always available
(e.g., on darwin). They should not be called unless available: gamma,
gammaf, scalb, scalbf, significand, and significandf.

libgomp/ChangeLog:

	* testsuite/lib/libgomp.exp: Add effective target.
	* testsuite/libgomp.c/simd-math-1.c: Avoid calling nonstandard
	functions.
