[PATCH] MachO-embedded: refactor Clang to use "*-*-unknown-macho" triple

[Rafael Ávila de Espíndola]

  The patch is OK by me.

  It is all MachO specific, so I would suggest getting someone at Apple to take another look. Another thing you might want to do is to split the patch a bit to make it easier to read. Some possible sub patches.

  * Rename DarwinTool to MachOTool.
  * Update the method names to start with a lowercase letter.
  *

----------------
nit: Usually there is no advantage in having inline virtual methods (other than the destructor) in non final classes.
