Can we do the same when removing files from sysroot?

To catch errors like this:
http://git.openembedded.org/openembedded-core/commit/?id=6b12d4cd39bacb087654b59e25f5052a4e839b26

12:40:15 < JaMa> it depends on order of tasks
12:41:27 < JaMa> gettext-native depends on gettext-minimal-native, so gettext-minimal-native installs own config.rpath to sysroot (when gettext-native "owns"
                 it too)
12:41:55 < JaMa> then gettext-native is built and before populting sysroot it removes own files there (including config.rpath)
12:43:45 < JaMa> and because sstate assumes that every file in sysroot is provided by exactly one recipe, gettext-minimal-native looses his config.rpath
12:44:49 < JaMa> now there is at least warning when 2 recipes are installing the same file to sysroot, but that doesn't resolve this issues when some file is
                 "moved" between recipes
12:47:30 < JaMa> because gettext-minimal-native is only recipe installing it
12:47:39 < JaMa> and gettext-native is only removing it

If we check manifests from other recipes before removing files we can show warning that
gettext-native is trying to remove config.rpath now provided by gettext-minimal-native
and keep config.rpath in sysroot.

Now everybody doing incremental builds needs to call
bitbake -c cleansstate gettext-minimal-native

Cheers,
