x11 static compile fail

[Rafi Rubin <rafi@seas.upenn.edu>]

Compiling a static x11 program fails using the output of:
	pkg-config --static --libs x11

The problem appears to be -lpthread shows up only before -lxcb.  There's
something a bit odd in the pkg-config files.  x11.pc has pthread in
Libs.private, and xcb has pthread-stubs in Requires.private.  However
pthread-stubs isn't actually adding the -l flag to the output, and the
resulting ordering breaks my build.

So, which package should be correct: x11 or xcb?  Should the
pthread-stubs have -lpthread in Libs.private?


My versions:
ibxcb1-dev 1.11.1-1
libx11-dev 2:1.6.3-1
libpthread-stubs0-dev 0.3-4
