Subject[PATCH 12/14] Remove AT_VECTOR_SIZE_ARCH on x86
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.
