[PATCH] Adding fenv support arm.

I removed the __softfloat_float_raise option and there seems some progress
Still log is showing some unrecognised option errors.
The function that required _softfloat_float_raise
I returned return (excepts  ?  -ENOTSUP : 0); from there
and there seems no new error.
But might require testing for other functions and arguments.

Log:

*eshan at EDs-pc*:*~/development/Tools/tmulti*$ ./multilib_cycle_gcc.sh
as: unrecognized option '-meabi=5'
as: unrecognized option '-meabi=5'
as: unrecognized option '-mfloat-abi=hard'
