I think something like the following can work and solves the problems with the
current situation:

Compile libmesa.a once in Mesa and use it both for Mesa and Xorg, Xorg still
needs source linking but only for a small number of files from drivers/x11 and
glapi (for glx).

The problematic defines are:
- IN_DRI_DRIVER
- USE_XSHM
- XFree86Server
- XFree86LOADER (IN_MODULE, NO_LIBCWRAPPER)
- _XSERVER64
- USE_EXTERNAL_DXTN_LIB

Barring the cases mentioned in comment #1, I think that
- USE_XSHM, XFree86Server, _XSERVER64 only affect drivers/x11 which will still
  be compiled within Xorg.
- XFree86LOADER is inactive (and can be dropped, bug #9144)
- IN_DRI_DRIVER can be handled with adding the driInitExtensions() patch to
  xm_api.c and a configure variable in Xorg, enabled by default on linux and
  freebsd.

This approach does not require adding new files to Mesa, only the changes to
xm_api.c and small changes to src/mesa/Makefile.
