The justification is that /usr/X11R6 is "special" -- it's a standard part 
of the FSH.  As long as X libraries are supposed to be installed there, 
it seems clear that the related .pc files should be placed in the same 
hierarchy.

If we can get the FSG to move the X libraries to /usr/lib, then pkg-config 
should change as well.
