I don't see XML::Writer.

I don't know.  I'm about to go on vacation, so I'll worry about this when I get 
back.  It's not relevant to the transition to perl-5.22.0.  My plan for the 
transition is to build biber-1.8 (x86_64 only for now), assuming it builds and 
tests OK once I have perl-XML-Writer.
