Also, I don't think is really is like USE flags.  Well, it's a very  
small subset of USE.  The specification here is simply more fine- 
grained detail on the architecture, and differs from specifying  
CFLAGS I guess only in that some packages will have custom code (like  
hand-written assembler or something) for different architectures.   
This is not definition a change in functionality of the package, but  
just a change in which implementation of the functionality to  
select.  Most USE flags specify a feature set to include/exclude --  
"iwmmxt" or "thumb" don't really change "features", but just the  
implementation details of those features.
