[Bug target/36031] New: ARM -fshort-enums attribute not emitted for Fortran

[drow at gcc dot gnu dot org]

The -fshort-enums option emits a note in the object file that the linker can
use to detect mismatches.  It does not work for Fortran; the "int-sized enums"
attribute is emitted with or without -fshort-enums.

I think this is a gfortran bug.  It implements its own short-enums flag instead
of using flag_short_enums.

Thanks!  I forgot to leave a note on how I encountered this, and I
don't remember :-(
