There's more targets that need the same treatment.

I'm trying to build webkitgtk 2.3.3 with make -j20 and it goes into
what looks like an infinite loop after a while. The -d output suggests
that it's a problem calculating the dependencies. make 3.82 seems to
fix that problem, so I updated and now I'm hitting this. I wonder if
they are related.

Btw, instead of touching the file you can just make the perl script regenerate it every time, even when it's unchanged.

Nah, my problem with make seems to be a different one since I'm not
using the one from jhbuild.

True, but there are now at least three different scripts that don't necessarily generate their intended output. Changing their behavior might also not work well with builds of other ports.

I think just additionally touching the output after it's generated is the easiest fix for this.
