I had added "-fnoinhibit-exec" to LINKFLAGS in linux/arch/ia64/Makefile
and got:
	ld -f may not be used without -shared
	make: *** [vmlinux] Error 1

So how do I "make references weak"?

Sorry, typo.  --noinhibit-exec

extern int foo __attribute__ ((weak));

It didn't complain. But it didn't help either:
