Fix fallback fesetenv and feupdateenv on FE_NOMASK_ENV (bug 17088).
This patch fixes bug 17088, fallback fesetenv and feupdateenv not giving an error for an FE_NOMASK_ENV argument when it requires traps to be enabled. (This is the bug tested for by test-fenv-return.c.) Tested mips64 soft-float. [BZ #17088] * math/fesetenv.c (__fesetenv) [FE_NOMASK_ENV && FE_ALL_EXCEPT != 0]: Return 1 for FE_NOMASK_ENV. * math/feupdateenv.c (__feupdateenv) [FE_NOMASK_ENV && FE_ALL_EXCEPT != 0]: Likewise.
