I have:

pavel@duo:/data/l/linux-n900$ arm-linux-gnueabi-gcc --version
arm-linux-gnueabi-gcc (GCC) 4.7.2
Copyright (C) 2012 Free Software Foundation, Inc.
pavel@duo:/data/l/linux-n900$ arm-linux-gnueabi-ld --version
GNU ld (GNU Binutils) 2.23.1.20121113
Copyright 2012 Free Software Foundation, Inc.

Let me try with eldk-5.6:

pavel@duo:/data/l/linux-n900$ arm-linux-gnueabi-gcc --version
arm-linux-gnueabi-gcc (GCC) 4.8.2
pavel@duo:/data/l/linux-n900$ arm-linux-gnueabi-ld --version
GNU ld (GNU Binutils) 2.24

make  lib/string.o

Seems to succeed, so I guess full build will succeed, too...
