su: FEATURE_SU_BLANK_PW_NEEDS_SECURE_TTY

When this feature is enabled, blank passwords are not accepted by su
unless the user is on a secure TTY defined in /etc/securetty. This
resembles the default PAM configuration of some Linux distros which
specify the nullok_secure option for pam_unix.so.

Based on patch by Kaarle Ritvanen <kaarle.ritvanen@datakunkku.fi>
