That should just 'not happen'. There has been one problem here: a bug in 
crunchgen emitting a line causing the wrong make to be used. This should 
not and was not fixed by causing the new .mk files to be usable with the 
old make but causing the right make to use in rescue. Otherwise you should 
obviously not forcibly use the old make with new .mk scripts or the other 
way around. The makefiles are usually smart enough to use either the new 
make and the new .mk files or the old, installed make and the old, 
installed .mk scripts. Any mismatch is either cause by a bug somewhere (as 
in the case of crunchgen) or forced by the user.
