something like: bitbake rpm-natice -c cleansstate bitbake rpm-native will not rebuild rpm-native, but will install the original from wr-prebuilts
Probably, remove wr-prebuilts from bblayers.conf and then rebuild.
Configure a project from a "dvd" installation (lx32, for example), build a project, or at least rpm-native, then attempt to rebuild rpm-native. This should apply to any host tool, but has not been tried.
