powerpc: Add option to use thin archives
Add an option to use thin archives to build the kernel. Thin archives are explained in commit a5967db9 ("kbuild: allow architectures to use thin archives instead of ld -r"). This is a gradual way to introduce the option to testers. Some change to the way we invoke ar is required so it can be used by scripts/link-vmlinux.sh.
