BLD: Use `-ftrapping-math` for clang and for `_so`
Apparently, there is a second `compiler_so` that is actually the
main compiler being used, and modifying only the first one is just
futile.
The old try was `-ffp-exception-behavior=strict`, but that seems to
be a fairly new addition (and doesn't even work on MacOS with 10.0)
`-ftrapping-math` seems to be the older, equivalent option.
