[PRQ#81204] Deletion Request for ghdl-gcc

smallAndSimple [1] filed a deletion request for ghdl-gcc [2]: See https://aur.archlinux.org/packages/ghdl#comment-1014367: "ghdl-gcc can be obsoleted, because GCC backend will be dropped." Paebbels, just for reference, is one of the primary maintainers of https://github.com/ghdl/ghdl. Now that vunit is compatible with ghdl (not ghdl-gcc), I think its time to retire the package.
