FFmpeg编译错误：arm-linxu-androideabi-gcc is unable to create an executable file

执行configure.sh
/develop/program/sdk/androidndk/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc-4.4.3 is unable to create an executable file.

解决方法：
创建临时文件：export TMPDIR="D:/FFmpeg/temp"，添加后的代码如下所示:

#!/bin/sh
NDK=C:/Software_Install_Files/Android/sdk/ndk-bundle
SYSROOT=$NDK/platforms/android-21/arch-arm
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/windows-x86_64
export TMPDIR="D:/FFmpeg/temp"
