  Modified files:
    lib/libc_r/uthread   uthread_create.c uthread_init.c 
                         uthread_sig.c 
  Log:
  For the amd64 we need to do some extra stack alignment fixups.  Otherwise
  we can end up with some threads with a non-16-byte-aligned stack.  This
  causes some interesting side effects, including general protection
  faults leading to a SIGBUS when doing floating point or varargs.  This
  should be just a verbose NOP for the other platforms.
