mock not reporting rpmbuild errors

[Jeff Sheltren]

Hi, is anyone else seeing this issue with current versions of mock?   
If rpmbuild exits with an error, mock proceeds happily as if the  
build succeeded.  This is really annoying when building with plague,  
for example, since even if the build fails, the job gets added to the  
'Successful Builds' list, and I won't get an email with the build  
error sent to me.

I opened a BZ for this a couple of weeks ago, but it hasn't been  
responded to:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=246614

Thanks,
Jeff
