The -u ones are from the universal binary, which was stripped.  The others
were from the native binaries.  And I don't even know what's up with that
last one, from the native ppc bin.  The data in the rest of the file seems
okay, though.

This appears to be only a problem with stripped binaries.  After building an
unstripped UB, the signatures match for i386.  I'm still not sure what's up 
with ppc.

There was an issue with the __bss and __common sections being incorporated into 
the MD5 checksum
generating the ID.  Since these two sections are "virtual" they contain no 
actual data on disk.  Nevertheless,
bogus data was read from the file (which has a different arrangement fat vs. 
nonfat).

Patch attached.
