I just ran into the exact same problem, and here is a links to a LFS manual
stating the problem as well :
http://archive.linuxfromscratch.org/lfs-museum/4.1/LFS-BOOK-4.1-HTML/chapter06/glibc.html#AEN2505

So yes I think that should be good to ship nsswitch.conf.

For information, I used the nsswitch.conf file found in my external toolchain
sysroot that was re-created under buildroot, in my case it was at

<buildroot_path>/output/host/usr/sh4-unknown-linux-gnu/sysroot/etc/nsswitch.conf

Kind regards,
Lionel
