Subject: [PATCH] silo: Allow building tilo only

The bootloader bits are built as 32-bit, which can be difficult to do on
a system with a 64-bit userland since they include system headers.

Specifically, the inclusion of <gnu/stubs-32.h> is problematic since
this header is not provided on a non-multilib build of glibc.

	<gnu/stubs-32.h>, included by
	<gnu/stubs.h>, included by
	<features.h>, included by
	<elf.h> and <setjmp.h>

tilo is built for the host machine and doesn't have this problem.
