No, it's not an error, and it can't be suppressed because it's important.

What it's telling you is that these functions from glibc use the libnss 
external library to perform their functions (so they can consult 
/etc/nsswitch.conf and use different methods of hostname/address 
resolution). In spite of the fact that you static-linked against glibc, 
if you want these functions to work you will need to still supply a copy 
of the libnss that was used at link time. It means you don't really have 
a completely static binary.

uClibc and other libcs don't work this way, so they don't have this problem.
