Allow fesetround failures in math/test-misc.c if ROUNDING_TESTS fails

[Joseph S. Myers]

This patch adds further tests of ROUNDING_TESTS to math/test-misc.c,
to avoid failure of fesetround resulting in the test failure for
rounding modes not expected to be fully supported.  This stops this
test failing for soft-float MIPS.

	* math/test-misc.c (main): Ignore fesetround failure when failures
	of subsequent rounding tests would be ignored.
