Hmm must do something odd then.

Yes, which means if cross-building works it must be requring a separate
walk of the tree or similar dance.
It cannot work by building tools like make_keys in the same pass as the
library, since that would require use of something other than CC.

Yes, that's for ccache, but I don't see HOST_CC used anywhere.

Sorry, guess I have no clue how cross-building currently works in
FreeBSD, but as is it won't work with DIRDEPS - which pretty much
expects to be able to build the tree in a single pass.

META_MODE should be orgthogonal, but that appears not to be so.
