libc build failure

[abwillis]

With newer binutils fnstsw changes from using %ax to %eax: src/msun/i387/fenv.c int _STD(feupdateenv)(const fenv_t *envp) {

• int mxcsr, status;

+ int mxcsr; + uint16_t status;

fnstsw(&status); if (HAS_SSE())

stmxcsr(&mxcsr);

else

mxcsr = 0;

fesetenv(envp); feraiseexcept((mxcsr | status) & FE_ALL_EXCEPT); return (0);

}

A define may need to be created to determine which binutils is used.
