chrome/android still used system gcc as host compiler, and system gcc is gcc 4.6 on Ubuntu Precise. This is too old. Instead, use clang by default as host compiler (except when building for AOSP, see http://crbug.com/377684 for that). This is controlled by a new gyp variable host_clang, which only has an effect if clang=0. The existing clang gyp variable means "use clang for everything"; if it's not set then host_clang means "use clang for host compiles". If your system gcc is 4.8+ and you don't want to use clang, you can set host_clang=0 to use system gcc for host compiles instead. In host_clang mode, our clang plugins currently aren't used (I figure if you want plugins, you can just use clang=1). clang_warning_flags on the other hand are used, to make sure the build stays warning-free.
