You can't keep them in lock step anyway - do a mesa build and install
it, then udpate mesa to a incompatible version and do an xserver build
and they're out of sync even with our current symlink technique.  The
underlying problem is that the glapi interface is part of the DRI
drivers and if it ever breaks, the DRI driver interface breaks.  This
won't change whether we symlink or not.  I don't think it's a big
deal, but breaking the compile time dependency on mesa source is
major, in my opinion.
