It doesn't change anything in this respect, the only difference is that
object directories are created for all cases. The problem is solved
much easier if you don't try to make Make go beyond what it is designed for.
(This applies to autotools too.)
Basically, what you're trying to do is to build multiple configurations.
Canonical approach is not to do that. With autoconf you're supposed to use
separate build directories:
for l in sbcl gcl; do (mkdir obj.$l; cd $l; ../configure --with-$l); done
If you really want to do that in autoconf correctly, you have to create
additional layer that does something like this:
