    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:

    (cherry picked from commit d912fcfb65224c7c11644d1332ec382edb102cec)
