Update.
* 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.
