It was added to build(7) in r338043:

     LOADER_DEFAULT_INTERP  Defines what interpreter the default loader
                            program will have.  Valid values include “4th”,
                            “lua”, and “simp”.  This creates the default link
                            for /boot/loader to the loader with that
                            interpreter.  It also determines what interpreter
                            is compiled into userboot.

Correct.  The loader and its support files (4th and lua) are built by
'make buildworld' and installed by 'make installworld'.  The source code
is in /usr/src/stand.

The freebsd-boot partition contains the code that loads the loader and
should not need updating.
