- Add -fdiagnostics-color so that compiler warnings are colorized. The way Ninja invokes GCC disables colors by default. - Move -Wno-psabi up to the arm_gcc_toolchain template so that it doesn't have to be specified for each arm_gcc_toolchain instance. - Add -Werror to the strict_warnings config to prevent warnings from slipping through. Exempt a few warnings that should actually be warnings. Change-Id: I8656d6690b488f7b004f15abd7100b62e1945cfd
