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.
