mtklein 7d6fb2c92d GN: Android
Once you have downloaded an android NDK, you can set the ndk GN arg to use it.
E.g. my gn.args looks like:
  is_debug = false
  ndk = "/opt/android-ndk"

This should be enough to get you going for an arm64 build.  You ought to be able to tweak that to other architectures by changing target_cpu to "arm", "x86", "x86-64", etc.  That won't quite work until I follow this up a bit, but the skeleton is there.

This is enough to get me compiled, linked, and running to completion on my N5x.
