* elf/dl-support.c (_dl_aux_init): Honor DL_PLATFORM_AUXV.
* sysdeps/unix/sysv/linux/alpha/dl-auxv.h: New file. * sysdeps/unix/sysv/linux/alpha/dl-support.c: New file. * sysdeps/unix/sysv/linux/alpha/dl-sysdep.c (__libc_alpha_cache_shape): Move to dl-auxv.h; initialize instead of extern weak. (DL_PLATFORM_AUXV): Move to dl-auxv.h; don't test for undef weak symbol. * sysdeps/unix/sysv/linux/alpha/sysconf.c (__libc_alpha_cache_shape): Extern instead of initialized.
