From b1919cfb4a2ec955423e6cf8ccc6afabc8ffb3ed Mon Sep 17 00:00:00 2001
From: Hidehiko Abe <hidehiko@google.com>

Subject: Remove unnecessary diffs from libchrome.

- Update build_config.h.
- platform_test.h had a modification to support Mac tests. Because we drop
  Mac host support, that change is no longer needed.

Bug: 73270448
Test: Treehugger.
Change-Id: I82affa36a4e055368f08ee7554e38eedc61fa6e1
