Perhaps worth a shot.  However, for something as complex as the kernel I
wouldn't count on getting a binary-identical kernel even if you just did
two builds in immediate succession.  Certainly if the compiler and
toolchain wasn't identical you wouldn't expect identical binary results.

Comparison at a level other than md5 might work - you could get big
chunks that are the same.  Also, looking at symbol tables or something
like that might help.  I'd have to figure out how to do it though -
never really had cause to tear apart the binaries like that.
