    Revert "Fixes a problem when executing initltool-merge -m in po/ directory."
    
    This reverts commit b4d33d9ee56d97aa39cd67355dacdfdaa7bf7d0a.
    
    It reverts this commit because this change is causing problem building
    chronojump on OSX. I temporary disable this change (next commit will
    have a workaround for the intltool-merge) since we need to build on OSX
    as well.
