mac平台下LuaJIT-2.1.0-beta2 编译android i686-linux-android-clang: Command not found

今天更新luajit2.1beta2时，编译android一直报错。

阅读最src/Makefile发现增加了这么一句

ifeq (Windows,$(findstring Windows,$(OS))$(MSYSTEM)$(TERM))
  HOST_SYS= Windows
  HOST_RM= del
else
  HOST_SYS:= $(shell uname -s)
  ifneq (,$(findstring MINGW,$(HOST_SYS)))
    HOST_SYS= Windows
    HOST_MSYS= mingw
  endif
  ifneq (,$(findstring CYGWIN,$(HOST_SYS)))
    HOST_SYS= Windows
    HOST_MSYS= cygwin
  endif
  # Use Clang for OSX host.
  ifeq (Darwin,$(HOST_SYS))
    DEFAULT_CC= clang
  endif
endif

在mac下编译默认用的clang, NDK是没有i686-linux-android-clang，

修改成默认gcc做了一个判断

  # Use Clang for OSX host.
  ifeq (Darwin,$(HOST_SYS))
    ifneq (Linux, $(TARGET_SYS))
      DEFAULT_CC= clang
    endif
  endif

贴上 luajit 编译代码
