mips: clear condition bit 23 in fpu too
We've been carrying this in Gentoo for quite a long time to fix some test
failures that people hit.
Original message:
> make[4]: *** [/glibc/glibc-package-2.3/mips-linux/obj/math/test-fpucw.out] Error 1
This test fails since the read back fpu control word is 0x80000 instead
of 0x0. I wonder if this patch is correct:
...
which additionally masks out the condition bit 23 - note that the other
condition bits (25-31) are masked out too?
