okay, please read the commits, my message was only providing
a tiny bit of context. This is for systems which do not provide
an ldd.so.conf (which exist), however...

... I think that you are right here and a simple -Wl,-R/path/to/X11
should do it (manual, or by the build facilities of the packaging
system). We do however need the -ljpeg unless I interpreted the
message I got from #guix the wrong way.

The changes had nothing to do with my system btw, it build okay with
it before these changes. Only because I am affected doesn't mean it
didn't work for me.
