powerpc: do not build ppc_save_regs.o always

The Fixes commit below tried to add CONFIG_PPC_BOOK3S to one of the
conditions to enable the build of ppc_save_regs.o. But it failed to do
so, in fact. The commit omitted to add a dollar sign.

Therefore, ppc_save_regs.o is built always these days (as
"(CONFIG_PPC_BOOK3S)" is never an empty string).

Fix this by adding the missing dollar sign.
