Summary: SHA 256 doesn't match test vectors on AMD64

Initial Comment:
On my Macintosh PPC G4 laptop:

>>> hex(bytes_to_long(SHA256.new('abc').digest()))
'0xBA7816BF8F01CFEA414140DE5DAE2223B00361A396177A9CB410FF61F20015ADL'

On my Linux Athlon64 workstation:

>>> hex(bytes_to_long(SHA256.new('abc').digest()))
'0x551CE4769446B343295EA7F819BAE21157541986A4DE11AB46B2340EA9831F22L'

The former is correct the FIPS 180-2 test vector for
SHA-256.

I see that the implementation is by Tom St. Denis but
it is very different from the one in his current
libtomcrypt 1.0.

Perhaps we should upgrade to that version?

I tried to run test_hashes.py, but it is apparently
written for an older (?) version of sancho that the
sancho 2.0 that I just downloaded.
