This commit should fix issue #95

Hi David,
Are you sure this was the culprit? Doesn't /path/{A,B,C} expand to /path/A, /path/B and /path/C anyway?

I know, I tried the command manually on the commandline and there this worked fine.
I tried this on several machines with different OS and different environments. But I was not able to build this. The command always creaed this folder build/SOURCES,SRPMS,RPMS and so the following steps which are trying to work in the generated directories do not work.

OK, it seems brace expansions are not POSIX-compliant (although bash and most other shells do support them).

I'm fine with the patch then. Before I merge it, though, please also do the same correction under the clean: target where we do rm -f $(BUILDDIR)/{SOURCE,SRPMS,RPMS}/*.

@dmnks I added the changes in the clean: target.

Merged, thanks!
