This applies to all platforms unlike the GYP change and the change below.

Shouldn't we have isolate files for all platforms? (If not, this is different
from the others.)

Thanks for the catch. Since this variable wouldn't be used on anything but
Android (at least initially), GN will give an error when building on other
platforms (I got "ERROR Assignment had no effect." when trying to build on linux
just now). Moving into the if(is_android) block.
