Comment (by egall@…):

 Replying to [comment:3 djvasi@…]:
 > This seems to be breaking Tiger/ppc. Building ld64 fails because
 CPU_SUBTYPE_ARM_ALL and friends are undefined. Since the dtrace package
 isn't installable on Tiger, xnu-headers can't be installed, and there's no
 way to get a recent mach/machine.h.

 I think that's a different issue...
