  Add assembly sha1 implementation for ppc We don't use it yet, but now we have it there at least. All the non-trivial parts of it appears to have been written and contributed to git.git by some anonymous genius. The original implementation was done by Paul Mackerras <paulus@samba.org>. Signed-off-by: Andreas Ericsson <ae@op5.se>
