hmm, i see, so how about going about it another way. instead of trying to do this at compile/link time, do it an load/runtime. one way of doing it would be to preserve a page in .rodata then map in a code page underneath that holds your empty function (which you can generate from C). it'd be somewhat similar to how the vsyscall page on amd64 is mapped (or used to be mapped) from the kernel image into its userland visible place.
