There's no such thing as Makefile.ac. configure.ac is processed by
autoconf, and Makefile.am is processed by automake. If you want to
share values across multiple Makefiles, it sounds more like an automake
question for what to put in your Makefile.am. So I'm not quite sure how
best to answer your question, other than to say that yes, automake
supports nesting sub-projects with their own configure.ac while still
allowing the child projects to inherit values substituted in the parent
project configure.
