The work I needed to do to make various softfloat emulation behaviours
runtime-selectable for Arm FEAT_AFP has left the fpu code with very
few remaning target ifdefs. So this series turns the last remaning
ones into runtime behaviour choices and switches the fpu code into
"build once" rather than "build per target". The main driver of this
is that we're going to want to do this for the "multiple targets in
one binary" work.
Indeed the following 332 symbols are now removed for each target:

Thank you a lot for this huge help! :)
