That's pretty much what I suggested, but it doesn't remove the etra
complexity to the Makefile.autotools.in rules (there's a generic set
of rules going $(BUILD_DIR)/%/.stamp_<something>:). The package
settings for the other things are done with ?= <default>, so adding a
$(2)_BUILDDIR ?= $(BUILD_DIR) would be enough.
