[PATCH 3/6] xorg: Build a glamor_egl module.

[Eric Anholt]

This is not exposing the API we want long term, but it should get
existing DDX drivers up and running while we massage the API into
shape.

v2: Use LIBADD instead of LDFLAGS to fix deps on libglamor.la, and use
    version 0.5.1 (the point it was forked from the external repo).
