Nice.  I added a variant of this, after having burned myself by using my
scripts for testing across this change.  We can delete the code some
time down the line, but for now this should reduce the pain of
transition for people.  I dropped the test for the file existing -- I
want to replace the previous file there, not just leave an old one in
place.

# Provide compatibility with scripts for the old Mesa build system for
# a while by putting a link to the driver into /lib of the build tree.
all-local: i965_dri.la
	$(MKDIR_P) $(top_builddir)/$(LIB_DIR);
	ln -f .libs/i965_dri.so $(top_builddir)/$(LIB_DIR)/i965_dri.so;
