Update.
2001-01-05 H.J. Lu <hjl@gnu.org> * 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.
