Seems you skipped the initial bit, where it explains that the .la has
the full path.

"The particular problem with these .la files is that they have hardcoded
paths in them. So, for example, if /usr/lib/libgnome-menu.so just
contains the information that it requires libglib-2.0.so.0 but
/usr/lib/libgnome-menu.la says that it wants /usr/lib/libglib-2.0.la, it
causes libtool to link against /usr/lib/libglib-2.0.so at link time.
This is fine for a lot of typical build scenarios, but the dirty hacks
that jhbuild plays to get it to sandbox your system understandably
breaks. "

That's not enough, the .la files add libraries in /lib and /usr/lib.
Fedora has for instance already removed the .la files. Other
distributions are working on it (even Debian).
