From 237277e9a8133c64026b736b1427141e71655330 Mon Sep 17 00:00:00 2001

Subject: Moved guard_setup to dl-osinfo.h (used commonly by ldso and libc).
 Renamed to _dl_setup_stack_chk_guard, as in glibc. SSP requires now
 binutils-2.16.1 and newer. Add NOT_IN_libc/IS_IN_libc. Began using -DSHARED
 in uClibc_main.c, there are more candidates in there. Move back
 dl_protect_relro to it's earlier place.
