You're quite right and your solution above is indeed the sensible way to
write it :-) However, I'd just been reading about the new features added in
make 3.81 and was experimenting.

Still, having make throw a segmentation fault is bad so I figured it was
worth reporting the issue so that the problem could be fixed.  After all, the
next person to run into the same bug might not be using such a simple
makefile with easy alternatives.
