You are missing the other libraries. Here is what my buildroot config
options look like for my buildroot using an external glibc toolchain:

BR2_TOOLCHAIN_EXTERNAL_LIB_C="libc.so.6"
BR2_TOOLCHAIN_EXTERNAL_LIBS="ld.so.1 libcrypt.so libdl.so libgcc_s.so libm.so libnsl.so libnss_dns.so libnss_files.so libpthread.so libresolv.so librt.so libstdc++.so libutil.so"

The libraries that you do not have which are preventing you from logging
in our 'libnsl.so' and 'libnss_dns.so' and 'libnss_file.so'. Once those
are in your root filesystem, you will be able to login.
