To build everything:
./build-x264.sh

To build for arm64:
./build-x264.sh arm64

To build fat library for armv7 and x86_64 (64-bit simulator):
./build-x264.sh armv7 x86_64

To build fat library from separately built thin libraries:
./build-x264.sh lipo

这个非常好，支持各种架构,同时还支持neon，效率高。

奇怪了，为什么在我的mac os x 10.10.5 , xcode 7.1.1
编译的时候生成的libx264.a没有导出函数呢。
当我只编译arm64版本的时候生成的libx264.a是有导出符号的呢？

  脚本默认是编译多个架构到一个 .a 里
  你可以通过 lipo -info libx264.a 可以看到它包含了arm64 armv7s x86_64 i386 armv7 这几个架构
