bk2site & thcrut updates

[Michael Coulter <mjc_(_at_)_bitz_(_dot_)_ca>]

Some diffs for bk2site and thcrut are available at

http://bitz.ca/openbsd/thcrut.update

and

http://bitz.ca/openbsd/bk2site.update

Note: thcrut seems to core with a bus error
      on sparc64, when running thcrut discover -O x.x.x.x
      If anyone with a functional gdb could help
      track this down, it would very much
      appreciated.
