build simulator

build simulator是build一個跑在x86上的android
不過這功能到了後面就沒在maintain了

但還是試了一下
果真要改很多地方

my AOSP codebase
gingerbread-release
GRI40

1. framework 
1. strchr return type  : const char *  ->  char *  :   const_cast(strchr(..)) 
1. media/libmedia/MediaScanner.cpp
2. media/libstagefright/NuHTTPDataSource.cpp
3. media/libstagefright/httplive/M3UParser.cpp
4. media/libstagefright/rtsp/MyHandler.h
5. media/libstagefright/rtsp/ASessionDescription.cpp
2. external/gtest
1. Android.mk : remove external/stlport/stlport in libgtest_includes (stlport wont be built for simulator, so we try not to include stlport's headers )
3. external/libnfc-nxp
1. Android.mk 
1. remove libdl in LOCAL_SHARED_LIBRARIES (libdl wont be build for simulator, and we also need to modify build scripts to make it link against to libdl on my host pc)
2. remove -mapcs -mno-sched-prolog -mabi=aapcs-linux -mno-thumb-interwork in LOCAL_CFLAGS
3. add LOCAL_C_INCLUDES := bionic/libc/kernel/common for libnfc
2. Linux_x86/phDal4Nfc_i2c.c 
1. add "#include
3. Linux_x86/phDal4Nfc.c
1. add "#include
2. remove line 664: pthread_setname_np(pthread_self(), "reader");
4. development/simulator/
1. app/DeviceWindow.cpp 
1. line 175: bool hasAlpha = onionSkinImage.HasAlpha(); -> bool hasAlpha = onionSkinImage.GetAlpha() != NULL; 
2. app/MainFrame.cpp
1. remove line 239, 280 : menuHelp->AppendSeparator();
5. build
1. core/combo/TARGET_linux-x86.mk
1. TARGET_GLOBAL_LDFLAGS := $(HOST_GLOBAL_LDFLAGS) -m32 -lpthread -ldl -lrt
6. packages/apps/Nfc
1. ./jni/com_android_nfc.h
1. add "#include

although I can build a simulator 

but it still cannot run Android well
