tests/fp/berkeley-testfloat-3: Ignore ignored #pragma directives

Browse Source 
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.

Having:

  $ cc -v
  Apple clang version 13.0.0 (clang-1300.0.29.30)
