configure: Don't pass -mfp16-format to MSVC on ARM
The check for this option does succeed - MSVC accepts the option, but prints a warning about it being unknown and ignored, for each compiled object file: cl : Command line warning D9002 : ignoring unknown option '-mfp16-format=ieee' The configure script only attempts to add this option on ARM, therefore this warning isn't seen by the majority of people building with MSVC. Making this option into a no-op probably isn't entirely right, but on the other hand, we don't want to litter the code that checks for support for the option with compiler specific conditions either.
