    build: work around automake-1.15 & intltool complaining about translations in build dir
    
    make distcheck runs a build in dist directory subtirs and then runs intltool -m
    which in turn complains about translations in a built file.
    
    The issue is reported to intltool upstream already:
    https://bugs.launchpad.net/intltool/+bug/1117944
    
    (cherry picked from commit 5a4d03515a41b646c21ebc6cc61a8aa99cc1f904)
