configure: remove unused checks for functions

Browse Source 
Nothing uses the results from these checks, so remove the checks. There
are some "uses" in order to suppress macro shadowing in MSVC's
implementation of `isinf` and `isnan` as macros, but those are
hard-coded and do not require checks to manage.
