GCC tossed COFF debug info some time ago, so I think it's okay to
remove that from GDB as well.

We used to need this for building the DJGPP port of Emacs, but that is
no longer required, since the next release 31.1 of Emacs will no
longer force or need the -gcoff switch to GCC.  So that reason is also
no more valid.
