    graphics/mesa: Fix port when elfutils is installed
    
    By default when building in a clean env (i.e. poudriere) libelf from base
    will be used.
    When building with an unclean env and if devel/elfutils is installed build
    system will be confused and use libelf headers from ${LOCALBASE}/include but
    libelf from base.
    
    Fix this.
