use build-aux

Now that we use git, it's much easier to move directories around without losing 
history (compared to how things were in CVS).  I'm committing this patch to 
head, and a similar one to the branch, to use the build-aux directory, 
consistent with other GNU projects, rather than . on the branch and ltdl/config 
on head.

Subject: [PATCH] For consistency with other GNU projects, use build-aux 
directory.

* configure.ac (AC_CONFIG_AUX_DIR): Change ltdl/config to
build-aux.
* bootstrap (config_aux_dir): Likewise.
* Makefile.am (config_aux_dir): Likewise.
* ltdl/m4/gnulib-cache.m4: Use --aux-dir option.
