Well, this is a new ABI rather than a new hardware architecture. You could 
define a new set of macros for detecting ABIs. But it is treated as a distinct 
architecture in the compiler and OS, so I'm not sure a different set of macros 
is a good idea. Also I'm not aware of any other precedents.

PS: I like ARCH_X86_X32 more.
