[C++ Patch] Remove old bison hack?!

[Paolo Carlini]

Hi,

a few days ago I noticed this comment and code. Removing it passes 
testing on x86_64-linux (I would in any case also boot and test multilib 
before committing).

Admittedly, a bit risky, but Stage 1 seems the right time to try.

Thanks!
Paolo.
