[PATCH v2] autoregen.py: handle aclocal

[Sam James <sam@gentoo.org>]

We need to run aclocal which came up earlier with the binutils intl/ drop
(syncing with gcc).

The autotools docs recommend not running it manually but the setup we have
is unconventional.

Check for where we are and force an include path if needed. Also, pass --force.
