[POWERPC] Change ppc_rtas declaration to weak
Change the definition of powerpc's cond_syscall() to use the standard gcc
weak attribute specifier which provides proper support for C linkage as
needed by spu_syscall_table[].
Fixes this powerpc build error with CONFIG_SPU_FS=y, CONFIG_PPC_RTAS=n:
arch/powerpc/platforms/built-in.o: undefined reference to `ppc_rtas'
