Automake projects are expected to be self-contained and not refer to 
anything outside of the package.

Configure substitutions (AC_SUBST) cannot work because Automake includes
are expanded only once, when Automake is run.

The generated Makefile.in file (which gets processed by configure) does
not contain the include commands at all.
