smpfatal08 fails on systems where all cpus are started by the boot-loader and
thereby clobber the test output. This patch stops the secondary cpus with a
call to _CPU_Thread_Idle_body(). Tested on RISC-V and SPARC.

Subject: [PATCH] smpfatal08: block secondary processors
* On some SMP platforms, all cpus are started by the
boot-loader. We need to block the secondary cpus or they
will clobber the test output.
