Installworld failed on HEAD

[Matthew Dillon]

::Hi all,
::
::Both kernel and world are built with buildkernel and buildworld.  New
::kernel is installed before installing the world.
::I got following error from cpdup during installworld:
::Fatal error 'Cannot allocate red zone for initial thead' at line 263
::in file /usr/src/lib/libthread_xu/thread/thr_init.c (errno = 12)
::Seems to be related to recent libthread_xu changes.

:     I will look into fixing cpdup... I think I can adust it so it does
:     not initialize the threading system if it isn't being run with a
:     threading option.

    cpdup can't be hacked.  libthread_xu pre-initializes threading whether
    the program creates any threads or not.

    installworld should be using the cpdup built in the bootstrap stage.
    What I will do is make buildworld build a version of cpdup without
    pthreads for the bootstrap binaries.  That should work around the
    issue.
