But that kind of ifdeffery is not a good template to follow, is 
it?  Gas can get away with it, because you can't really create a 
multi-ISA assembler (not counting flavors within each of e.g. 
"intel" and "arm" families as different).

Honestly, when doing this larger level of work, why not create 
such a mechanism, one that would even work with 
--enable-targets=all?
