undefined reference to `xz_crc64'

[Jiri Gaisler]

I updated RSB and RTEMS to git head. RSB built fine for sparc, but
building the libtests/tar01 RTEMS test now fails with:

mv -f .deps/initial_filesystem_tar_xz.Tpo .deps/initial_filesystem_tar_xz.Po

tar01 used to build without issues, any ideas ...?
