      tools: prevent js2c from running if nothing changed · f645cc73
      Daniel Bevenius authored
      This commit updates tools/js2c.py to touch the target output file
      , <(SHARED_INTERMEDIATE_DIR)/node_javascript.cc, even if the content
      has not changed. This is to "help" the build system so that it can
      compare the inputs against the output to determine if the gyp action
      should be run.
      
      I believe the issue here is that if js2c.py is updated this can
      cause the action to be run as the node_javascript.cc target would be
      older than js2c.py. But when the target is run the timestamp for
      node_javascript.cc will not be updated (because we have not changed
      anything that would change the contents of the file) so the js2c.py
      prerequisite will always be passed and the target always run.
      
      Using the update in this commit one would have to touch/modify one of
      the js files specified in the library_files list, config.gypi, or
      tools/js2c.py for this action to be run again.
