<li>
The sim target itself is broken under 64-bit Linux.
This is because the sim target is based upon some assembly language setjmp/longjmp logic that only works on 32-bit systems.
<p><small><b>NOTE</b>: There is a workaround in this case; you can build for 32-bit execution on a 64-bit machine by adding <code>-m3</code> to the <code>CFLAGS</code> and <code>-m32 -m elf_i38</code> to the <code>LDFLAGS</code>.</small></p>
