Removed targets and configurations that are no longer functional

are below.

  + Force CPU386 - This BSP was developed as part of the initial
    port of RTEMS to the i386.  This board has been unavailable
    for a long time now.

  + GO32 - This BSP and some CPU code supported djgpp v1.x.  This
    version is now quite old.  No one has stepped forward to
    update the code to v2.x which may be technically impossible
    anyway.  More importantly, go32 has been superceded by the pc386 BSP.
