related patch from opensuse's KOTD kernel.src.rpm 

Description of problem:
The problem described in http://bugzilla.kernel.org/show_bug.cgi?id=11143 happens on F9 these days. Quoting that bug:

"""
arch/powerpc/Makefile
...
     77 ifeq ($(CONFIG_PPC64),y)
...
     93 else
     94 LDFLAGS_MODULE  += arch/powerpc/lib/crtsavres.o
     95 endif
...

if external modules are build against the source tree, then linking will fail
because there is no arch/powerpc/lib/crtsavres.o binary.

I see a make scripts and make prepare target, which copies
/usr/src/linux/scripts sources to /usr/src/linux-obj/<arch>/<flavor>/
Maybe the ctrsavres.S has to be copied as well?

Now, if I knew how kbuild works, I could provide a patch. But I do not know, so
I opened this bug in the hope that it gets fixed for 2.6.26.1
"""

In the end it looks like this:
"""
  ld -m elf32ppc -r   arch/powerpc/lib/crtsavres.o --build-id -o /home/thl/rpmbuild/BUILD/qc-usb-kmod-0.6.6/qc-usb-0.6.6/quickcam.ko /home/thl/rpmbuild/BUILD/qc-usb-kmod-0.6.6/qc-usb-0.6.6/quickcam.o /home/thl/rpmbuild/BUILD/qc-usb-kmod-0.6.6/qc-usb-0.6.6/quickcam.mod.o
ld: arch/powerpc/lib/crtsavres.o: No such file: No such file or directory

"""
That was building of qc-usb for ppc

Version-Release number of selected component (if applicable):
2.6.26.5-47.fc9.ppc

Additional info:
Seems suse has patch in their kernels; in the changelog I found
"""
* Mi Aug 06 2008 olh@suse.de
- add patches.suse/ppc-no-LDFLAGS_MODULE.patch
  do not link external modules against arch/powerpc/lib/crtsavres.o
"""

Same problem happens on F8.ppc; didn't check rawhide

P.S.:
Why is there no arch "ppc" in the "Platform" selection of bugzilla?
