package/gcc: disallow Fortran on gcc 12/13 on Microblaze

Browse Source 
The build of gcc with Fortran support is broken on gcc 12.x and gcc
13.x, it fails with:

../../../libgfortran/generated/bessel_r8.c: In function 'bessel_yn_r8':
../../../libgfortran/generated/bessel_r8.c:178:1: internal compiler error: in gen_reg_rtx, at emit-rtl.cc:1167

This issue has been fixed in gcc 14.x, which builds a Microblaze
Fortran-capable toolchain successfully.

Since we're not really interested in figuring out the commit that
fixed the problem, let's simply disallow the selection of Fortran with
gcc12/13 on Microblaze.

Fixes:
