Bug#763729: RM: mutter [kfreebsd-amd64 kfreebsd-i386 hurd-i386] -- ROM; ROP: no longer builds on kbsd
mutter currently requires libgbm, which is only available on Linux. I'm
requesting the removal of the ood binaries from !linux architectures,
until that dependency can be made optional and mutter can build there
again. Since the only rdep of mutter is gnome-shell, which is only built
on linux these days, this shouldn't be a problem.
See #763675 for the porters' comments on the matter.
