[PATCH] Reverse arguments of fdivp

- Subject: [PATCH] Reverse arguments of fdivp
When building libc on i?86, gas complains:
../sysdeps/i386/fpu/bits/fenv.h:124: Warning: translating to `fdivp
%st,%st(1)'. This patch corrects this issue. Tested on i686-linux,
ok for trunk?

* sysdeps/i386/fpu/bits/fenv.h (feraiseexcept): Reverse the
operands of fdivp instruction.
