  This happens because buildroot uses the --strip-components=1 option of
tar to remove the leading path component - and now this is just the '.' that
is removed.

  If the boost maintainers could repackage the tar file without the leading .,
that would be really nice for us.  If not, we have to construct a workaround
in buildroot to treat the boost extraction specially. (Aras: you can probably
just add "/boost_1_51_0" to all the references to $(@D) in the .mk file.)

  This you can ignore: you're extracting in /tmp which isn't owned by
you, so you can't change the metadata of /tmp.  All files are still
untarred, it's just the exit code that's not 0.
