Wait, why is this only for Mac? It is not included conditionaly through #if
defined(OS_MAC) in base/build_time.cc.
https://chromium.googlesource.com/chromium/src/+/master/base/build_time.cc#8

[NGG, 2016/02/18 23:31:48]

Because build_time.cc is not compiled for non-mac targets (see below at line
388)

[brettw, 2016/02/19 22:13:48]

This seems wrong. Why did you add build_time.cc only for Mac? It's
unconditionally compiled in Chrome.

[NGG, 2016/02/20 14:58:44]

It's only needed on Mac because //base/memory/shared_memory_mac.cc includes
//base/metrics/field_trial.h and that has additional dependencies. It's not
needed on Linux for compiling GN.

+    # and this file is only included for Mac builds.
