[PATCH 2/4] powerpc/64: do not link crtsavres routines into vmlinux

[Nicholas Piggin <npiggin@gmail.com>]

The 64-bit linker creates save/restore functions on demand. crtsavres.o
is still required to link against modules (which do not get their
save/restore created automatically, due to not being a final link).

Make crtsavres.o extra-y on 64-bit, rather than obj-y.
