cygwin编译错误.

编译其他的jni项目是可以的.

但是编译 weex_v8core

cd jni/v8core/v8 && TARGET_ARCH=armeabi ./build.sh
'TARGET_ARCH' 不是内部或外部命令，也不是可运行的程序
或批处理文件。
make: *** [jni/v8core/v8/out/android_arm.release//obj.target/tools/gyp//libv8_base.a] Error 1

报错

Start with jni/v8core/v8/build.sh and the make target for jni/v8core/v8/out/android_arm.release. Reproduce the failure in the reported Cygwin environment and determine why the TARGET_ARCH assignment is rejected; done means the weex_v8core build completes successfully.
