出错1：
host C++: obbtool <= frameworks/base/tools/obbtool/Main.cpp
:0:0: error: "_FORTIFY_SOURCE" redefined [-Werror]
:0:0: note: this is the location of the previous definition
cc1plus: all warnings being treated as errors
make: *** [out/host/linux-x86/obj/EXECUTABLES/obbtool_intermediates/Main.o] Error 1
解决办法：
在 ubuild/core/combo/HOST_linux-x86.mk 文件中：
找到行：
HOST_GLOBAL_CFLAGS += -D_FORTIFY_SOURCE=0
改为：
HOST_GLOBAL_CFLAGS += -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0

解决办法：
$ vim frameworks/compile/slang/Android.mk
将 local_cflags_for_slang 所在行最后的 -Werror 去掉：
#local_cflags_for_slang := -Wno-sign-promo -Wall -Wno-unused-parameter -Werror
local_cflags_for_slang := -Wno-sign-promo -Wall -Wno-unused-parameter
解决上述问题，编译，OK。
