[PATCH] siggen.py: If both sigs have a variable in it's whitelist then don't say it's changed

[PATCH] siggen.py: If both sigs have a variable in it's whitelist then don't say it's changed

[Matthew McClintock]

Some BB_HASHBASE_WHITELIST variables are in the lists of variable
dependencies for signatures. Ignore those differences in lists
since this difference does not matter

I'm seeing variables in BB_HASHBASE_WHITELIST make it
to the signature. Not sure if they are used to calculate
the hash but assuming they are not we don't need to print
out that they are different

Merged to master, thanks.
