That won't work right, the aux dir name needs to be known to autoreconf
and 'automake --add-missing', so it needs to be a literal string.
The reason autoconf doesn't warn or error out about nonliteral
AC_CONFIG_AUX_DIR argument is probably that in the distant past
(2.13 I guess, before I knew Autoconf anyway) it used to be
possible to pass a shell variable.
Cheers,
Ralf
