Can you try using the else-if feature in GYP?

I think this can be written as:

['OS=="android"', {
  'platform': 'android'
}, 'chromeos==1', {
  'platform': 'chromeos'
}, 'OS=="linux"', {
  'platform': 'linux'
}, ...
}, {
  # This will cause the script to fail.
  'platform': 'unknown_target_arch'
}],

ooo, didn't know that was possible.  Done.
