For packages reported by xbps-checkvers as removed, generated makefile
finds files matching <pkgversion>.<arch>.xbps. This is needed to know
where is repodata in which package is indexed (path may contain
multilib, aarch64, nonfree subdirectories). Then, xbps-rindex is called
to remove package from stage index. Then, xbps-repodb needs to remove
package from public index when no other package depend on it. Finally,
xbps-rindex -r will remove package file.

When package is updated and marked not to build on some architectures
with archs/nocross/broken/restricted, it needs to be removed form
repository.
