[PATCH 0/3] Add fenv.h generic infrastructure and default implementations

This patch series adds generic infrastructure for fenv.h methods.
The file libc/include/fenv.h is the RISC-V one with no modifications.
The template/default libc/include/sys/fenv.h is derived from
the RISC-V but is just an arbitrary defintion of the required values.
I assumed the RISC-V implementation was correct per POSIX given
the high quality comments.

The first patch is to pick up some files which got regenerated
using the script Jeff emailed me. Not sure about those but I
included them. Note: When bootstrapping, don't forget I added
libm/fenv/Makefile.am.

Second patch is the core of the work.

Third patch is regenerated output from the files I touched.

I did test builds on sparc-rtems5 and riscv-rtems5. The sparc
got default versions of fenv methods and the riscv got its own.

When merged and the RISC-V folks are happy, I think their 
specific implementation of fenv.h can be removed.

The SPU implementation has incorrect signatures. I have no
idea about that and no SPU experience.

Interested to hear comments.

Thanks.
