configure: only use -ffloat-store on i386
this option is expensive and only used on old gcc's that lack -fexcess-precision=standed, but it's not needed on non-i386 archs where floating point does not have excess precision anyway. if musl ever supports m68k, i think it will need to be special-cased too. i'm not aware of any other archs with excess precision.
