Sure. It will need a real host make, regardless.
But can't this be done like a ... host-make-old? Then your make variable
for that obnoxious package gets treated with a "older make" and the rest
of the world lives on like normal?
Ptxdist doesn't care, neither does the vast majority of packages. They
are going to be up to date and have fixed makefiles.

Yuck. :)

I got stuck on the new make with the really, really old gstreamer tools.
I've patched them (will send those in if anybody cares). So keeping up
with patches is also an alternative. But I'd rather be able to tell
ptxdist "older make here please".
