`C-h f compile' explains:

| (compile COMMAND &optional COMINT)
|
| Compile the program including the current buffer.  Default: run `make'.
| Runs COMMAND, a shell command, in a separate process asynchronously
| with output going to the buffer `*compilation*'.
|
| You can then use the command C-x ` to find the next error message
| and move to the source code that caused it.
|
| If optional second arg COMINT is t the buffer will be in Comint mode with
| `compilation-shell-minor-mode'.
|
| Interactively, prompts for the command if `compilation-read-command' is
| non-nil; otherwise uses `compile-command'.  With prefix arg, always prompts.
| Additionally, with universal prefix arg, compilation buffer will be in
| comint mode, i.e. interactive.

So:

(defun compile-target-at-point ()
  "Run \"make\" with the symbol at point as the target, via `compile'."
  (interactive)
  (compile (format "make %s" (or (symbol-at-point)
                                 (error "No target at point")))))

(global-set-key [f4] 'compile-symbol-at-point)
