I think this comment can just be removed - it refers to the
skia_libs_location_android setting which is commented out

[zra, 2013/05/28 16:56:16]

To make running tests easier, we'll likely also be building run_vm_tests for the
host architecture, which requires its own build target. I have that going under
this CL: https://codereview.chromium.org/16060004/. After that, it might make
sense to make a variable for the Android link settings rather than copying it a
third time, if possible.

[Bill Hesse, 2013/05/29 09:12:44]

I wasn't sure if the entire 'link_settings' section can be a variable, or only
flat lists, so I didn't make a variable yet.
Merged with your CL by putting the android linking only on the target target,
not the host target.
