AFAICS slapping subdir-objects within configure.ac is not an option(at least
not currently)

Something seems to be broken in your setup. subdir-object should work with out
of tree builds, and it seems to work great on my system (recent(ish) master +
subdir-object branch)

$ cd mesa && mkdir automake-build && cd automake-build
$ ../autogen.sh && make
$ cd ../
$ find . -name "*.so" -or -name "*.la" -or -name "*.a" -or -name "*.o" | grep
-v automake\-build | wc -l
0
$ git clean -nxd | grep -v Makefile\.in
Would remove aclocal.m4
Would remove autom4te.cache/
Would remove automake-build/
Would remove bin/*
Would remove configure
Would remove m4/*
Would remove src/gallium/auxiliary/util/*.pyc
Would remove src/mapi/glapi/gen/*.pyc
Would remove src/mesa/main/get_hash_params.pyc

With dricore gone I can revisit/update my branch and get some of the
autoconf/automake spam out of the way :)
