There are two versions of mathinline.h
sysdeps/powerpc/fpu/bits/mathinline.h
sysdeps/unix/sysv/linux/powerpc/bits/mathinline.h
Here's a diff between them. They're the same except for some recent additions
to the deeper file.

Even though the macros are guarded by !defined _SOFT_FLOAT we generally like to
keep any file with floating point assembler operations in a powerpc/fpu
directory. So I think it's better to go with the shallower version and move the
recent changes there and then remove the deeper one. Patch forthcoming.
