One reason could be that you linker is not aware of sysroot properly. As a result it does not append correct sysroot path and ends up looking at /lib which ofcourse it your host libc (x86) and hence the error. you might need to backport sysroot related patches to binutils 2.14

We have been able to build mipsel with angstrom-2008 I would suggest that you use those versions of toolchain and kernel headers for nylon to start with. Its gcc 4.2.4 binutils 2.18.x.x.x eglibc-2.9 linux-libc-headers 2.6.23
