Well, in that case, the only viable way is to not use AC_CONFIG_SUBDIRS,
but instead invoke the sub configure manually, probably best after
AC_OUTPUT, by extracting and re-quoting the needed arguments from
$ac_configure_args.  See autoconf/status.m4:_AC_OUTPUT_SUBDIRS for how
this is done.

Or, fix zlib/configure.  :-)
