* sysdeps/powerpc/elf/libc-start.c (AUX_VECTOR_INIT): Define it.

	(LIBC_START_MAIN, LIBC_START_MAIN_AUXVEC_ARG, MAIN_AUXVEC_ARG)
	(INIT_MAIN_ARGS): Define, and #include <sysdeps/generic/libc-start.c>.
	(__libc_start_main): Just call the generic one for most of the work.

	* sysdeps/generic/libc-start.c [LIBC_START_MAIN]: If defined, define a
	static function by that name instead of BP_SYM (__libc_start_main).
	[LIBC_START_MAIN_AUXVEC_ARG]: Take AUXVEC as argument.
	[MAIN_AUXVEC_ARG]: Pass 4th argument to MAIN.
	[INIT_MAIN_ARGS]: Give INIT the same args as MAIN.

	* sysdeps/generic/dl-sysdep.c (_dl_sysdep_start) [DL_PLATFORM_AUXV]:
	Use this macro for extra AT_* cases.
	* sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c (DL_PLATFORM_AUXV):
	New macro, guts from ...
	(__aux_init_cache): ... here, function removed.
	(DL_PLATFORM_INIT): Don't define this.

	* sysdeps/powerpc/powerpc32/memset.S: Put __cache_line_size in bss.
	* sysdeps/powerpc/powerpc64/memset.S: Likewise.

	* Versions.def (libthread_db): Add GLICB_2.3.3 set.
