[PATCH] kexec: build multiboot2 for i386

[Chris Packham]

This addresses the following compilation issues when building for i386.

I wasn't sure whether this should be fixed by linking with kexec-mb2-x86.o or
by removing the code from kexec-x86.c. I went for the former but I'd happily
change to the latter.
