On ARM, musl does not define FE_* when arch does not have
VFP, (which is right interpretation), therefore check if
it is defined before using it.

Fixes errors like:

tests/general/roundmode-pixelstore.c:82:19: error: 'FE_UPWARD' undeclared (first use in this function)
  ret = fesetround(FE_UPWARD);
                   ^~~~~~~~~

You'll need a #else that sets ret, otherwise you're pretty obviously
going to jump based on an uninitialised variable here :/

Erm, yeah, sorry about that.  Grabbing a patch that we've been
shipping without actually looking at it.

Okay, revised patch submitted, which hopefully does the right thing this time.
