* elf/dl-reloc.c (_dl_nothread_init_static_tls): Avoid using

THREAD_DTV multiple times, this minimally reduces code size on

* toutf8.c: Include stringprep.h first, to make the compiler check

that stringprep.h is standalone. Improve comments. Replace

#include of errno.h and sys/param.h with iconvme.h. Don't define

ICONV_CONST.

(stringprep_convert): Rewrite to use iconvme.h.
