[COMMITTED] Provide __libc_fatal for rtld.
Commit Message
This makes it possible to use __libc_fatal in rtld code.
Thanks,
Roland
* include/stdio.h: Add rtld_hidden_proto (__libc_fatal).
* elf/dl-minimal.c: For readability, reorder some definitions and
introduce more page breaks. Include <stdio.h>.
(__libc_fatal): New function.
