[Rpm-maint] AArch64 support

Hi,

Sorry for the late response, this has gotten buried in the rather 
unusual flood of mail and patches of late...

Hmm, aarch64 is not a "multilib architecture"? Or is it just to keep 
things simple by not allowing multilib despite the hardware being 
capable of it? (I'm mostly just curious, but also related to the libdir 
thing)

Hmm... this always was klunky, but adding individual archs as special 
cases is not going to work in the long run. So if aarch64 really isn't 
CANONCOLOR 3, I think its better to move the LIB setting into the above 
switch for the architectures that want it to make it clear and explicit.
