项目编译成动态库是正常的，将Android.mk里面的最后include $(BUILD_SHARED_LIBRARY)改成
include $(BUILD_STATIC_LIBRARY)编译静态库，运行NDK-BUILD却一点反应都没有，一闪而过。
从控制台中看：
Your group is currently "mkpasswd". This indicates that
the /etc/passwd (and possibly /etc/group) files should be rebuilt.
See the man pages for mkpasswd and mkgroup then, for example, run
mkpasswd -l [-d] > /etc/passwd
mkgroup -l [-d] > /etc/group
Note that the -d switch is necessary for domain users.
cygwin warning:
MS-DOS style path detected: C:\NDK\android-ndk-r6b/ndk-build
Preferred POSIX equivalent is: /cygdrive/c/NDK/android-ndk-r6b/ndk-build
CYGWIN environment variable option "nodosfilewarning" turns off this warning.
Consult the user's guide for more details about POSIX paths:

根本就没有编译源文件，而编译动态库就会有：
Compile thumb : dvnca <= dvn_cak.c
SharedLibrary : libdvnca.so
Install : libdvnca.so => libs/armeabi/libdvnca.so
解决办法有两种：
1、在Android.mk并行目录增加 Application.mk
文件内容：
APP_ABI := armeabi
APP_PLATFORM := android-9
APP_MODULES := libdvnca
2、在Android.mk中增加使用静态库的编译选项
include $(CLEAR_VARS)
LOCAL_MODULE := libdvnca
LOCAL_SRC_FILES := \
src/dvn_cak.c \
LOCAL_C_INCLUDES := \
$(LOCAL_PATH)/inc \
LOCAL_CFLAGS += -D__ANDROID__ -DTEST_IPANEL -DUSE_GRAPHICS_PIXEL_ALPHA -DHAVE_GFX_2D
include $(BUILD_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := test
LOCAL_STATIC_LIBRARIES := libdvnca
LOCAL_CFLAGS += -D__ANDROID__ -DTEST_IPANEL -DUSE_GRAPHICS_PIXEL_ALPHA -DHAVE_GFX_2D
include $(BUILD_SHARED_LIBRARY)
如此控制台输入的打印为：
StaticLibrary : libdvnca.a
SharedLibrary : libtest.so
Install : libtest.so => libs/armeabi/libtest.so
