Thanks for taking care of this. LGTM after the fact.

File gpu/khronos_glcts_support/BUILD.gn (right):

https://codereview.chromium.org/1413303003/diff/20001/gpu/khronos_glcts_suppo...
gpu/khronos_glcts_support/BUILD.gn:75: configs += [
"//build/config/compiler:rtti" ]
There's a fair amount of duplication of these configurations in this file -- is
it possible to common them up?

I tried to find a way to do this, but GN doesn't seem to make that easy.  The
thought was maybe to use a template, but I couldn't get templates to work
properly... we also discussed this a little in my first (abandoned) submission:

ullysses.a.eoff@intel.com changed reviewers:
+ ben@chromium.org, cpu@chromium.org, darin@chromium.org, jam@chromium.org

[U. Artie Eoff, 2015-10-29 01:12:57]

Looks like we still need Owner review for the ".gn" change.
