ia64 has an ugly chicken vs. egg build dependency. When trying to build our asm-offsets.h
file (to get #define constants for various structure sizes and offsets in a format that is
usable in assembly code) we get:

include/linux/sched.h:2539: error: 'IA64_TASK_SIZE' undeclared (first use in this function)

Which is sad because IA64_TASK_SIZE is one of the #defines that asm-offsets.h is trying
to produce.

Which is why I just threw up my hands in despair and said "!IA64" for this option.
