There are several functions involved.  In case of #<OBJNULL> using
traces I see that |compDefineCapsuleFunction| function (defined
in 'define.boot.pamphlet') gets:

 1> (|compDefineCapsuleFunction|
         (DEF (|base|) (NIL) (NIL)
              ((|elt| |Lisp| FLOAT-RADIX) (|elt| $ (|Zero|))))
...
...


It seems that (|elt| $ (|Zero|)) give us '#<OBJNULL>.  |elt| is
handled in 'compiler.boot.pamphlet':


    2> (|compForm1| ((|elt| |Lisp| FLOAT-RADIX) (|elt| $ (|Zero|)))

      3> (|compElt| (|elt| $ (|Zero|)) |$EmptyMode|
....
....
      <3 (|compElt|
             ((|call| (XLAM |ignore| '#<OBJNULL>)) $
