I've never tried this, but I had some ideas:

1. We already set SHELL=$(PTXDIST_TOPDIR)/bin/bash in
   rules/other/Toplevel.make so that handles some of it.
2. PTXdist itself is a problem. I had some ideas about re-executing ptxdist
   if the shell is different from $(PTXDIST_TOPDIR)/bin/bash.

That should help for PTXdist. Most files are not directly executed so the
shebang is just cosmetics.
