"make ARCH=ia64 headers_install" generates assembly errors

  the result of running:

$ make -d V=1 ARCH=ia64 headers_install

  the issue appears to be this snippet from arch/ia64/Makefile:

...
GAS_STATUS      = $(shell $(srctree)/arch/ia64/scripts/check-gas "$(CC)" "$(OBJDUMP)")
CPPFLAGS += $(shell $(srctree)/arch/ia64/scripts/toolchain-flags "$(CC)" "$(OBJDUMP)" "$(READELF)")
...

  this will obviously cause problems if you have no cross-compiler,
which you really shouldn't need if all you're doing is installing
headers, anyway.

  the headers_install step still works, but it would be cleaner if the
Makefile didn't try to do things like check for proper assembler when
there's no call for it.

Are these lines even useful anymore given the current tool chain we have?
