I'm not familiar with this library, and I haven't looked at current state of how we enable/map optional libs in a while...
We definitely want to avoid adding another target option/debug flag, and if we can avoid relying on a function parameter too, that would be even better.
Ie, the "afn" fast-math-flag (possibly in combination with some other IR- or node-level flags) seems like it should be enough to allow this transform/lowering. 
Scanning the earlier review comments, there was some concern about the semantics wrt errno. If we need to adjust the "afn" definition, it's probably fine. There haven't been many uses of that flag AFAIK.
