For a few years now, libtoolize has checked that the first -I <dirname> matches
the argument to AC_CONFIG_MACRO_DIR, when both are given, providing
a diagnostic error if they do not. Otherwise if only one of those is provided by
the calling project, it uses whichever is provided as the destination for
libtool.m4 and friends.
