So you removed them manually? I'd like to understand what happened, to
fix Buildroot if needed.

By default, we only copy libnss_dns (to do DNS resolution) and
libnss_files (to do /etc/hosts based resolution), and we don't copy the
other libnss_* libraries, which are used for more advanced name
resolution that are generally not used on most embedded systems.

See 'man nsswitch.conf' for more details.
