This is a way to fix the problem. libgcc/soft-fp/op-4.h has provided a C
version of __FP_FRAC_SUB_4, but now it is overrided by the inline asm version
in config/i386/32/sfp-machine.h.

But the inline asm looks legal right? Isn't it compiler's responsiblity to keep
the inline asm constraints always satisfiable?
