recipes/linux/linux-efika-2.6.20.20/weaken-div64_32-symbol.patch

   1 2.6.20.20 with CFS fails to compile for powerpc, because this arch already has
   2 its assembly-optimized __div64_32() implementation, so linking fails due to
   3 two symbols.

   5 The same issue appeared on the s390 arch, so this patch is inspired by it.
