That x86_64-*-* test is wrong.  x86_64-*-* and i?86-*-* should always be 
handled the same (if you then want to distinguish 32-bit and 64-bit 
multilibs, you check the appropriate effective-target there, depending on 
whether the condition is one on the ABI or which register size is being 
used, which affects how x32 should be counted).
