Wow, that is one ugly hack.  :(

I assume the real problem here is that download_toolchains.Main does not take
argv and instead uses sys.argv?  Maybe we should change that (as well as the
main here).

+  if 'chromeos=1' in os.environ.get('GYP_DEFINES', ''):
+    sys.argv = [
+      sys.argv[0],
+      '--nacl-newlib-only',
+      '--file-hash', 'linux_x86_newlib',
+           '8337d5ec327d857a49b500723ec9b792f4973abc',
+      '--base-url', ('https://commondatastorage.googleapis.com/'
+                     'nativeclient-archive2/special_chromeos'),
+      '--x86-version', '6561',
+    ]
   script_dir = os.path.dirname(os.path.abspath(__file__))
   src_dir = os.path.dirname(script_dir)
   nacl_dir = os.path.join(src_dir, 'native_client')
