I previously said I used this option because I was not to build for 64  
bits, and only for 32 bits. However, after a review of [1], it appears  
Multiarch is not just about cross compilation or compilation to a  
different instruction set on the same architecture, that's also about a  
standard directory layout. May I have to guess Multiarch should be enable  
depending on the directory layout of the target environment also and not  
only depending on the target instruction set or architecture?

If so, as Debian always use Multiarch, and as my target is both Ubuntu  
(for my machine) and Debian (for a server), even if the target is to be  
ia32 only, then I should still enable Multiarch. Do I understand correctly?
