RFE: Makefile.common patch to error out when no spec is present

[Kevin Fenzi]

Greetings. 

I know some of you have run into this situation: 

If you have a package where there is no *.spec file present and you try
to run any of the fedora cvs Makefile.common targets, nothing happens
and the command just hangs. 

Turns out it's doing a grep of the spec file to figure out if the
package is noarch or not. When there is no spec file the grep hangs. 

Here's a very hacky patch that should at least error out in this case. 

Makefile hackers welcome to provide a better one.
