Hi,

this version fixes build with binutils <= 2.19 by first checking if ar(1)
supports the D option. It depends on a previous patch in the kbuild tree,
commit 40df759e (kbuild: Fix build with binutils <= 2.19) in linux-next,
so it will need to go through the kbuild tree. But feedback from the PPC
maintainers would be appreciated.

Thanks
Michal
