i believe i've fixed the hang problem (see attached patch). here's
my current findings with the binaries provided with qemu and
the qemu-glibc tarball.

hello-i386 -> runs with or without the patch below
ls-i386    -> runs with the patch below, hangs without it
test-i386  -> runs with the 3 exceptions: the func_lret32 and func_iret32
              tests both die with a SIGSEGV. Also i get "Unsupported syscall:
			  252" when the program exits. i'm looking into both of these.

anyone know what changed to cause the label offsets to be off by 4?

nall.
