I fixed the whole thing some time ago with the patch from
http://lists.samba.org/archive/samba-technical/2006-October/049810.html

Or better take the following, the lists.samba.org archive is broken with
pgp signed messages:

The reason why that patch was not committed was that Jelmer said that %
isn't supported by non-GNU make implementations. I'm still not sure
about that but maybe you can figure out if make supports % in configure
and use that (or not) in the makefile accordingly then?
