Some packages install "build-aux" files (config.guess, config.sub,
install-sh et al) so that their add-ons can rely on them.
It would seem to be a relatively easy:
===== configure.ac
AC_PATH_PROG(foo_path, foo)
aux_dir=`foo -print-config-dir`
AC_CONFIG_AUX_DIR($aux_dir)
=====
Automake currently expects the argument to AC_CONFIG_AUX_DIR to be a
shell literal. That might be a regression, I haven't checked. I'd
need to look though what it takes to lift the restriction (there might
also be assumptions like that in Autoconf).
