It wasn't there before changing the package to use AC_CONFIG_MACRO_DIRS
instead of ACLOCAL_AMFLAGS.

In previous versions of Automake these same warnings will show up when
invoking aclocal without any -I options.  In this case, not passing
those arguments would be an error, and the resulting configure sript
would probably not work since aclocal can't find the macros in question.

But now, aclocal is being called with no -I options intentionally, and
it is actually finding the macros (and producing working configure
scripts), but these warnings are still being printed.  Adding the -I
options again makes the warnings go away.
