only required for android, no? Just move it down below the if platform() ==
'android':

It's the opposite, actually. We do not want a snapshot_blob.bin file hanging
around when v8_use_external_startup_data is disabled.

Moved this into a new "if platform() != 'android':"

   if platform() == 'android':
     print 'Clobber: To delete stale generated .java files.'
     print 'Delete stale generated .java files again. crbug.com/349592'
