I found a patch after the 0.13.0 release that switches from hardcoding
pkg-config to using the PKG_CONFIG environment variable and falling back
to pkg-config, so I backported it to 0.12 and was able to use that and
guix's regular pkg-config package.  I've added those patches to the
wip-zig-bootstrap tree.

We now have a couple of phases that are before the 'build phase, do you
think it'd be better to consolidate them into a 'configure phase?
There's no 'configure' script to run, but it does do a lot of
preparation before the actual 'build phase...
