Unfortunately, the people who wrote PowerPC support for glibc did
not create a sysdeps/powerpc/fpu directory containing FP-specific code.
There currently is no way to disable FP code in glibc-2.1, but I believe
that the maintainers were suppose to fix this for glibc-2.2; I do not know
about the status. People who have been working on Linux for embedded
processors have been building glibc somehow, but I do not know the details.
