Makefile: update scripts when build-time parameters change

Currently, running:

  make SHELL_PATH=/bin/bash &&
  make SHELL_PATH=/bin/sh

will not rebuild any shell scripts in the second command,
leading to incorrect results when building from an unclean
working directory.

This patch introduces a new dependency meta-file to notice
the change.
