Browse Source 
* 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.
