[libgfortran,patch] Remove stubs for unimplemented environment variables

Subject: [libgfortran,patch] Remove stubs for unimplemented environment variables

Attached patch removes the stubs present in libgfortran for some
unimplemented GFORTRAN_ environment variables: GFORTRAN_MEM_INIT,
GFORTRAN_MEM_CHECK, GFORTRAN_SIGHUP, GFORTRAN_SIGINT,
GFORTRAN_FPU_ROUND and GFORTRAN_FPU_PRECISION.

I agree with Tobias' analysis in PR32021 that there are better ways to
do each of these, and since it was decided some time ago to keep the
number of environment variable at its lowest, I think the right thing
here is to get rid of them.

I'll commit this in 48 hours unless someone disagrees.
