Note some libc implementations don't implement setting errno on math functions
(e.g. Darwin) and for those targets, -fno-math-errno is already the default.
So if you don't need to check errno, then you can use -fno-math-errno. C/C++
allows for an implementation to set errno on an error for math functions even.
So this is more about you wanting something different from what the
implementation does ...
