	* elf/dl-support.c (non_dynamic_init): Move the auxiliary
	vector checking to ...
	(_dl_aux_init): Here. New function. Defined only if
	HAVE_AUX_VECTOR is defined.

	* sysdeps/generic/libc-start.c (__libc_start_main): Call
	_dl_aux_init for static binaries if HAVE_AUX_VECTOR is defined.

	* sysdeps/powerpc/elf/libc-start.c (__libc_start_main): Call
	_dl_aux_init.

	* sysdeps/unix/sysv/linux/ldsodefs.h (DL_FIND_AUXV): Removed.
	(HAVE_AUX_VECTOR): Defined.
	(_dl_aux_init): Declared.
