Actually, it's a libtool issue. It's acceptable to say you've got to
rebuild libX11 when libxcb-xlib goes away since it was using symbols
from it. Nothing else should matter, but it does because tons of .la
files have been infected with an unnecessary reference to
libxcb-xlib.la.

Debian (and Ubuntu by proxy) has a patch that makes libtool only add
needed libraries (i.e., those added on the command line) to the
dependency_libs setting in .la files. Unfortunately, I think it still
has a few corner case bugs that make it not upstream acceptable. I
think this is it:
