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.
