: Agreed. In multiple cases I just wanted to populate the object tree

: expect those targets to actually do the cross-build. The build

For 'complicated' builds like this, I typically just do a make
buildworld -DNOCLEAN... 'make everything' traditionally has used host
tools... Since this builds < 30 minutes for me, I've not been too
motivated to fix things.
