lib/msun: Exclude ignored-pragmas from -Werror

This avoids build failures due to the clang 12 warning:
    '#pragma FENV_ACCESS' is not supported on this target - ignored

Clang 12 currently emits this warning for all non-x86 architectures.
While this can result in incorrect code generation (e.g. on AArch64 some
exceptions are not raised as expected), this is a pre-existing issue and
we should not fail the build due to this warning.
