Adding fenv support for ARM

Back on the list. :)
Thanks for making sure everything on the branch was up to date.
I decided take a simple shot. I disabled anything in sys/fev.h that looked
like it would conflict with an implementation in a C file.
$ git diff

Let's proceed a bit with this "if 0" in place. The code in that block may
be simpler to delete if it isn't used by the libm/arm/fenv-XXX.c files.
That got it building again but when I looked in the installed libm.a, it
was clear that the arm specific code wasn't in the library. I did the
following command and searched for "<fe" to see the fenv methods, what
assembly code was there, and what file was compiled to produce it:
$ arm-rtems5-objdump -da --source ../install/arm-rtems5/lib/libm.a| less
I then looked in the build log and fenv-vfp.c wasn't compiled. That was the
most obvious arm specific file name. Looking in libm/arm, I did this:
joel at localhost arm]$ grep fenv- Makefile.*
Makefile.am: fenv-vfp.c \
Makefile.am: fenv-softfp.c
Makefile.in needs to be regenerated. Or you can simply hack and add those
to the Makefile.in if that's all you added to the Makefile.am.
