wine: handle all *-config scripts

We already had a patch to allow us to explicitly pass the location of
the sane-config script, but wine's configure script uses several other
*-config scripts. This commit extends the wine patch and wine.mk to
explicitly pss the location of all *-config scripts that may be used
by wine.

The wine patch has been submitted upstream.
