Since we already use -Wno-unknown-pragmas, we can also use
-Wno-ignored-pragmas. This silences hundred of warnings using
clang 13 on macOS Monterey:
[409/771] Compiling C object
tests/fp/libtestfloat.a.p/berkeley-testfloat-3_source_test_az_f128_rx.c.o
../tests/fp/berkeley-testfloat-3/source/test_az_f128_rx.c:49:14: warning:
'#pragma FENV_ACCESS' is not supported on this target - ignored
[-Wignored-pragmas]
#pragma STDC FENV_ACCESS ON
^
1 warning generated.

$ cc -v
