Hm.  GNU make DOES reset the stack to the "normal" value (at least it
should) before it execs any commands.  It's only during the running of
GNU make itself that the stack is set to be unlimited.

We do this after we fork, and before we exec the command.

I don't see why having GNU make's stack set unlimited would impact GNU
make's children, unless there is some reason why resetting the stack
doesn't undo the change...?
