I'm getting ahead of myself today.  Autoconf has AC_CONFIG_AUX_DIRS as
an internal macro, but no AC_CONFIG_MACRO_DIRS.  I was mislead by the
fact that our existing libtool test doesn't use AC_CONFIG_MACRO_DIR in
the first place; so the first step is to improve the testsuite.
Meanwhile, the name AC_CONFIG_MACRO_DIRS is free for the taking.
