Patch to buildsys-build.spec to support SuSE SLES

[John Villalovos]

Attached is a patch which adds support for SuSE Linux Enterprise
Server (SLES) to the buildsys-build.spec file.

It is kind of ugly, since they use a lot of RPMS in their build
environment.  I haven't tried to trim it.  I used the information from
Matt Domsch that he has posted at
http://linux.dell.com/files/mock/buildgroups/sles10/i386/

I hope this is useful for others.
