Comment(by snc@…):

 I'm thinking we shouldn't check what architecture we're on -- as you
 indicated there is a blur of ppc on intel hardware through Rosetta.  This
 will only go away in the future (and who knows, we might pick up doing
 ARM).

 Why not simply check that they're trying to build a legit Mac architecture
 and leave it at that?
