+NETBSD_OFFICIAL_RELEASE
+               If defined and set to "yes", the build targets an official
+               NetBSD release which is going to be available from
+               ftp.NetBSD.org / cdn.NetBSD.org. This modifies a few
+               default paths in the installer and also creates different
+               links in the install documentation.
+               The auto-build cluster uses this variable to distinguish
+               "daily" builds from real releases.

 NOCTF          Don't generate and manipulate CTF data of ELF binaries
                during build. It is set internally for standalone programs.
