* elf/elf.h: Define AT_EXECFN.
* elf/rtld.c [!__ASSUME_AT_EXECFN] (process_envvars): Don't handle LD_ORIGIN_PATH. * elf/dl-sysdep.c (_dl_sysdep_start): Handle AT_EXECFN. * elf/dl-support.c: Define _dl_execfn. Don't define _dl_origin_path if __ASSUME_AT_EXECFN is defined. (_dl_aux_init): Handle AT_EXECFN. * sysdeps/unix/sysv/linux/kernel-features.h: Define __ASSUME_AT_EXECFN for 2.6.27 and up. * sysdeps/generic/ldsodefs.h (rtld_global_ro): Add _dl_execfn. Don't define _dl_origin_path if __ASSUME_AT_EXECFN is defined. * sysdeps/unix/sysv/linux/dl-origin.c (_dl_get_origin): Use _dl_execfn if available and avoid compatibility code if __ASSUME_AT_EXECFN is defined.
