Changeset bc2f04f in rtems for c/src/lib/libcpu/powerpc/wrapup

Patch rtems-rc-20000104-13.diff from Ralf Corsepius <corsepiu@…>
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.
