4.0-编译错误解决方法

Exynos 4412/4212 bsp默认是在64bit的linux下编译的，现有的linux系统是32bit，所以有一些需要改变。

1. build/core/combo/HOST_linux-x86.mk

HOST_GLOBAL_CFLAGS += -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0

2. external/yaffs2/Android.mk

#jeff. LOCAL_CFLAGS+=   -Wmissing-prototypes -Wredundant-decls -Wnested-externs -Winline

3. external/mesa3d/src/glsl/linker.cpp:1394:49: error: expected primary-expression before a€?,a€? token

增加： #include

4. external/oprofile/libpp/format_output.h:94:22: error: reference a€?countsa€? cannot be declared a€?mutablea€? [-fpermissive

external/oprofile/libpp/Android.mk

LOCAL_CFLAGS := $(common_host_cflags)  -fpermissive

external/oprofile/pp/Android.mk

LOCAL_CFLAGS := $(common_host_cflags)  -fpermissive

5. In file included from external/gtest/src/../include/gtest/gtest-param-test.h:157:0,

external/gtest/src/../include/gtest/internal/gtest-param-util.h:122:11: error: a€?ptrdiff_ta€? does not name a type

增加： #include

或 #include

6. frameworks/compile/slang/slang_rs_export_foreach.cpp:249:23: error: variable a€?ParamNamea€? set but not used [-Werror=unused-but-set-variable]
