x32 abi is a new abi which is different from x86_64 and x86.Some softwares
cannot compile on x32 system,but glibc,gcc,binutils,works well on x32 abi
 with faster speed than x86_64.So I would to make such a gcc version,its
abi is x32,but its default target is x86_64,similar to cross compiler.Then
I can build a x86_64 system with faster speed.The question is how to make
such a gcc version?

You need to set the right flags for it.  I think this was explained in the dev 
mailing list.  But ... I am not sure if the small difference in speed is worth 
potential breakage?  Will all packages in portage build without problems?
