I would personally suggest allowing something like the variants in the  
configure line:

architecture=i386,x86_64,ppc,ppc64

Having gone through something similar on other projects and with other  
build systems. Don't try to out-think the user just do what they ask.  
And if they don't ask for anything then give them the default for the  
platform they are compiling on.

Just my 2 cents.
