The "install" target isn't supposed to build stuff, only install it.
When you see it trying to build something, this can be indicative of:

- build wasn't run (e.g., after an update);

- a computer's date/time is set to the past (causing wrong date/time
  to be set on output files => causing them to be considered out-of-
  date by make(1)); check with date(1).

- source files have modification times pointing to the future which
  fools make(1) into thinking that it should rebuild some target;
  check with "find /usr/src -mtime -0".
