Is this a bug of binutils

[Li Zhijian <lizhijian@cn.fujitsu.com>]

Hi，all

I got a big problem when using the cross-toolchain to compile a simple C program.
This problem since 3ae71c74c71f13a390b21b4c3ead04e51aaa82b8
which is to upgrade the binutils from 2.22 to 2.23.1

what I do is as follows, any help or ideas ?

I) Build my cross-toolchain
# git clone http://git.yoctoproject.org/git/poky/.git
# cd poky
# git checkout 3ae71c74c71f13a390b21b4c3ead04e51aaa82b8 -b tcmode-default
...skip some steps...
# bitbake meta-toolchain
Loading cache: 100% |############################################################################################| ETA: 00:00:00
Loaded 1122 entries from dependency cache.

Build Configuration:
BB_VERSION = "1.17.0"
BUILD_SYS = "x86_64-linux"
NATIVELSBSTRING = "CentOS-6.3"
TARGET_SYS = "x86_64-poky-linux"
MACHINE = "qemux86-64"
DISTRO = "poky"
DISTRO_VERSION = "1.3+snapshot-20130912"
TUNE_FEATURES = "m64"
TARGET_FPU = ""
meta
meta-yocto
meta-yocto-bsp = "tcmode-default:3ae71c74c71f13a390b21b4c3ead04e51aaa82b8"

..cost a long time..
all of the build work successfully

II) Install my cross-toolchain
# ./poky-eglibc-x86_64-x86_64-toolchain-1.3+snapshot-20130912.sh
Enter target directory for SDK (default: /opt/poky/1.3+snapshot): toolchain-1.3-tcmode-default

III） compile a simple C program
# cat test.c
int main ()
{
printf("hello world\n");
return 0;
}
# source toolchain-1.3-tcmode-default/environment-setup-x86_64-poky-linux
# $CC -o test test.c -L tmp/sysroots/qemux86-64/usr/lib/ -lm
test.c: In function 'main':
test.c:3:9: warning: incompatible implicit declaration of built-in function 'printf' [enabled by default]
