Adding fenv support for ARM

I compiled the fenv-vpf.c and got this output.
output file:
https://github.com/eshandhawan51/rough_notes/blob/master/gcc_fenv-vfp.txt

A strange thing happened today I reset the branch to the previous commit
from removing the inline functions from sys/fenv.h
and the redefinition error disappeared and the error changed.
