While building Android with latest host gcc, it causes the following build error: Install: out/host/linux-x86/bin/mkbootimg host C++: obbtool <= frameworks/base/tools/obbtool/Main.cpp <command-line>:0:0: error: "_FORTIFY_SOURCE" redefined [-Werror] <built-in>:0:0: note: this is the location of the previous definition cc1plus: all warnings being treated as errors In order to make build system happy, this patch does unset macro _FORTIFY_SOURCE and then define it in host cflags.
