toolchain build error with eglibc on OpenWrt

[lingwang@altaitechnologies.com]

Hi developers,

I'm encountered a problem when I build OpenWrt's toolchain for Cavium
Octeon,which is mips64 r2 architectural.the error message as follow:
 My toolchain units version:
   gcc: 4.7.x
   binutils: 2.22
   eglibc: 2.17 (svn version 22243)

error msg:
