Oops, scratch that last thing; it doesn't depend on how GSL libs were
compiled. The fast-math optimization is done at link time and would
affect GSL library calls as well.
I don't see a significant difference (on x64) if fast-math is enabled,
though, even when doing lots of GSL library calls e.g. integrating
special functions.
