Building the Chromium port for Android requires us to cross-compile using the Android NDK's toolchain. Furthermore, as we'll be using OS=android, several gyp files and platform-specific files need to be taught how to handle this.
Can this just be dup'd into bug 66687?
Actually, all of WebKit builds, so this bug can be closed as fixed. I'll update 74089 to block 66687 instead.
