Actually it's just include.pro - everything else gets copied to the sysroot 
for the new machine just fine.

I've sort of figured this out. include.pro is getting installed to the sysroot  
and not ${D} in do_install (and it's the only file handled this way). I'm 
guessing that because of this it never gets picked up by sstate.
