Just look for brace expansion in spec files.  It's use is *extremely* 
common.  And many of the failures are silent, e.g. arguments to “rm -f”.

We could patch rpmbuild to run them using bash instead, but this example 
makes it very doubtful to me that Ubuntu and Debian have already done 
all the hard work for us.
