Then use host, dig, nslookup.  They don't use the glibc resolver.

I don't like this customization one bit since it introduces yet another
error source.  A program's behavior is different if a local resolv.conf
is used or if nscd is running.  This just means maintenance nightmares.
 And no, using "but it is done for file XYZ" is no argument.  I wouldn't
add these envvars today either.  Early mistakes.
