Patch rtems-rc-20000104-13.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>

which does the following:

  * some cleanups, fixes, addtions to the libbsp automake transition
    patches
  * The missing Automake transistion patches all libcpu/<cpu>/<variant>/*
    previously not yet been converted to automake (libcpu/powerpc,
    libcpu/hppa1.1, libcpu/mips64orion, libcpu/sparc)

  => With this patch, libcpu/*/* is under full automake control.

  NOTES:
  * This patch is tested by building for random set of bsps affected by
    this patch, but not tested for all BSPs.
  * The parts of this patch related to libcpu/powerpc fix many small bugs
    inside of those Makefiles.
  * Have a look into libcpu/powerpc/mpc6xx/, which is in rather bad shape,
    IMO. Obviously most subdirectories seem to be build but are not included
    into libcpu.a by wrapup/Makefile. Addtionally, no actual BSP uses this
    cpu-variant subdirectory. Furthermore libcpu/powerpc/mpc6xx has a
    different directory layout than all other powerpc/<variant>/
    directories.

    Joel's note:  I agree but the issue is that there is a conflict between
    including timer or clock in libcpu/XXX/wrapup/Makefile.* and letting
    a BSP specifically decide to pick it up.  There is no clear solution
    to this at the moment.
