Building minimal rootfs to use as non-root on arm device

Hello,

I have created a rootfs using buildroot, but using a crosstool-ng toolchain with glibc. This showed me the minimal set of files necessary. I then replaced all the libraries with ones pulled straight from the squeeze .deb packages for armel. I then added fakeroot and fakechroot to the mix. I also modified the resolv.conf, hosts, and nsswitch.conf files to my liking. After uploading this to my device, a lot is working. "cd /" takes me to the correct place. "whoami" returns root. But, anything DNS related is not working. For example "ping google.com" returns "bad address". I have copied the libnss_* and libresolv libraries over and everything else I think is necessary. Entering the same setup, but using qemu and chroot on my host machine works, but I am trying to figure out what it is not working on my target device.

When I run "strace ping google.com" I get the following:
