x86_64 Target Triplet

It has becoming known to the developers an issue with the x86_64 target 
triplet. It seems the maintainer of config.guess and config.sub has done 
something very silly, in my opinion.

In config.guess, if you search for x86_64 you will find the following line.

                 echo x86_64-unknown-linux-gnu

Which causes issues later on. We could fix this with a simple change, 
but every package would need to have the fix, if config.guess is 
present. The fix would be to
sed -i 's/x86_64-unknown-linux-gnu/${UNAME_MACHINE}-pc-linux-gnu/g' 

Now the issue is do we want to do, add the above hack, and live with 
every config.guess needing this change, or do we just leave it set to 

Opinions and alternative solutions are requested

Thank you all for you support.
