Fix math/test-nearbyint-except for no-exceptions configurations.
The test math/test-nearbyint-except conditions some of its tests on an EXCEPTION_TESTS call, not not all that need such a condition. This patch fixes it to use such a conditional for all its tests and to return 77 (UNSUPPORTED) if none of the floating-point types tested support exceptions. Tested for mips64 soft float (where the test previously failed and is now UNSUPPORTED); also tested for x86_64 to make sure the test still PASSes in exceptions-supported cases. * math/test-nearbyint-except.c: Include <stdbool.h>. (any_supported): New variable. (TEST_FUNC): Return early if !EXCEPTION_TESTS (FLOAT). Otherwise set any_supported. (do_test): Return 77 if no floating-point type supported exceptions.
