[erlang-bugs] Build fix for some architectures: x86_64 e.g. [resent]

[Rickard Green]

We will make sure that all applications use the same versions of 
config.{guess,sub} in R12B-1.

Christian: As I understand it, this will solve your problem. Am I right 
or wrong?

I googled a bit for new config.{guess,sub} files to use, and think that 
we will use the ones part of the latest stable libtool. Anyone objects?
