Cross compiling using separate output directory problems

[Peter Chubb]

Hi Sam,
   Thanks for doing the work to make comnpilation work with a separate
output directory.

I found the following changes necessary to get it to work properly
when crosscompiling for IA64.  Otherwise include/asm-ia64 hasn't been
created when setting up offsets.h.

There's also a minor change to tell make where to find the
toolchain-flags and check-gas scripts.
