Adding fenv support for ARM

[Eshan Dhawan]

hello,
There is error in the default fenv environment declaration  as it is
defined in libm/fenv
as well as machine/arm/fenv.c (the FreeBSD file added)
so should I add fe_dfl_evn.c file to machine/arm pointing to fenv_stub,ar
remove it from fenv.c file :)

error :
