It looks like there aren't actually users of this macro anywhere:
* The kernel doesn't use it on x86 because we don't suppor ELF FDPIC.
* The only Google results point to LMKL patches, both the one that wrote this (from 2010) and my patch to hide it behind __KERNEL__.
* I grep'd through all the source tarballs on my machine, and the only packages that matched were the kernel and crui (which copied a PPC kernel header).
Since I'm not sure how to actually provide the right answer (if I understand correctly, CONFIG_IA32_EMULATION is not __i386__), the only thing I can think of to do is to just remove the definition.
