Nsd-checkconf[3402]: error: md5 digest not available

When running in fips mode, the below error appears.

It comes from tsig_openssl_init_algorithm() and is generating a
log_msg() but for some reason nsd-checkconf is sending this
message to stdout, causing the hourly nsdc rebuild cronjob to
output it, causing it to send emails.

Can this be suppressed either via a new -q option or by just logging
it at different levels or to syslog only?

Our brave new world no longer has MD5
