1.download Python-2.7.2 and Python-2.7.2-xcompile.patch
其他patch
2.解压Python-2.7.2.tgz
3.进到目录里 ./configure
4.make python Parser/pgen
5.mv python hostpython
6.mv Parser/pgen Parser/hostpgen
7.make distclean
//如果clean失败，则拷贝出以上两个备份，重新解压代码，再进行下面
8.patch -p1 < Python-2.7.2-xcompile.patch

错误：
exit 77 configure: error: C compiler cannot create executables
交叉编译工具链有问题，换一个即可

host 和 build 搞反了
重申：
host即一般arm
build：一般x86
