* elf/rtld.c (process_envvars): Call __strtoul_internal instead of
	strtoul.
	* elf/dl-minimal.c (strtol, __strtol_internal, strtoul): Removed.
	(__sigjmp_save): Set __mask_was_saved to zero since we don't save
	anything.
	* dlfcn/eval.c (__strtol_internal): Define here.
	(eval): Use __strtol_internal instead of strtol.
