I wish you'd sent this to the list a bit more promptly since the last
update to bug 44618 eight months ago. As it is now, I've got a large
(100) patch series in progress that touches these Makefile.am's.

Overall, it looks pretty good. I'm very glad to learn about the AX_
macros. I feel much better adding those to Mesa's build system than
macros like we have now (see MESA_PIC_FLAGS).

I'd like it if this could be made a patch on top of my
automake-gallium series,
