PowerPC floating point little-endian [12 of 15]
http://sourceware.org/ml/libc-alpha/2013-08/msg00087.html
Fixes for little-endian in 32-bit assembly.
* sysdeps/powerpc/sysdep.h (LOWORD, HIWORD, HISHORT): Define.
* sysdeps/powerpc/powerpc32/fpu/s_copysign.S: Load little-endian
words of double from correct stack offsets.

* sysdeps/powerpc/powerpc32/power5+/fpu/s_llround.S: Likewise.
* sysdeps/powerpc/powerpc32/power5+/fpu/s_lround.S: Likewise.
* sysdeps/powerpc/powerpc32/power5/fpu/s_isnan.S: Likewise.
* sysdeps/powerpc/powerpc32/power6/fpu/s_isnan.S: Likewise.
* sysdeps/powerpc/powerpc32/power6/fpu/s_llrint.S: Likewise.
* sysdeps/powerpc/powerpc32/power6/fpu/s_llrintf.S: Likewise.
