Below is a patch, which is supposed to fix this issue.

It filters out --prefix from ac_configure_args and explicitly prepends
--prefix=$ac_prefix to ac_sub_configure_args.

This ensures that the prefix used in a toplevel configure script will
always be passed down to subdir configure scripts, 
i.e 
* If a toplevel configure.in applies AC_PREFIX_DEFAULT, this value will
also be used in subdirs.
* If a user explicitly passed --prefix to the toplevel configure script,
this value will be appled to subdir configures, too.
* If a subdir-configure.in applies AC_PREFIX_DEFAULT, the value from the
toplevel configure will override it.
