remove older ones

df and nice are in /bin, not in /usr/bin.  This is important because busybox
puts these into the correct locations, and the different directories breaks
update-alternatives.

    - df can only be build if one of the many statvfs,fsusage
      was is present. These tests work by executing a test application
      and that is obviously not working out when cross compiling
    - all linux (glibc, eglibc, uclibc) should have the bsize in the
      struct statvfs... and this will enable the build of df.

    This is a partial revert of aa03004ace2fabb135a6208ef8c2d2b312aa7b0b. The
    approach that was taken leads to disagreement and the change was pushed
    too early. DISTRO_PR is going to say and will be used inside the package
    creation. There will be more disucssion on the list about where to continue
    from here.

    Allow a distribution to globally bump the PR of every package
    this is useful when there was a change in the toolchain and
    every package is going to be different.

    find packages/ \( -name '*.bb' -or -name '*.inc' \) -exec sed -i s/"^PR="/"FILE_PR ="/ {} \;
    find packages/ \( -name '*.bb' -or -name '*.inc' \) -exec sed -i s/"^PR ="/"FILE_PR ="/ {} \;
