There are two possible patterns to avoid having to repeat this in both the
outputs block and the actual action (which is what made this bug possible):

1.) Write "_outputs" in the action block; it'll be replaced with the contents of
the outputs block. Examples:
https://code.google.com/p/chromium/codesearch#search/&q=_outputs%20file:gyp&s...

2.) Have a variables block where you define a variable (e.g. named output_file,
but the name is up to you), and then reference that in outputs and action. One
example for this is
https://code.google.com/p/chromium/codesearch#chromium/src/build/android/dex_...

           'action': [
             'python', 'webapp/build-html.py',
             '<(output_dir)/unittest.html',
             '<(remoting_webapp_unittest_template_main)',
             # GYP automatically removes subsequent duplicated command line
             # arguments.  Therefore, the excludejs flag must be set before the
             # instrumentedjs flag or else GYP will ignore the files in the
             # exclude list.
             '--exclude-js', '<@(remoting_webapp_unittest_exclude_files)',
             '--js', '<@(remoting_webapp_unittest_cases)',
             '--instrument-js', '<@(remoting_webapp_main_html_js_files)',
            ],
         },
       ],
     },  # end of target 'remoting_webapp_js_unittest'
   ],  # end of targets
