* elf/dl-libc.c (do_dlopen_args): Add caller_dlopen.
(do_dlopen): Pass caller_dlopen to dl_open.
(__libc_dlopen_mode): Initialize caller_dlopen.
* intl/l10nflist.c (_nl_normalize_codeset): Make it compile outside
of libc. Make tolower call locale-independent. Optimize a bit by
using isdigit instead of isalnum.
