看来这玩意真是不可靠，系统/usr/include/中明明有selinux/selinux.h这个的，没法，在busybox的include目录:ln -sf /usr/src/selinux selinux
继续make

这次有点头大，查找一翻，是libpam0g-dev包没装，ok, sudo apt-get install libpam0g-dev
继续在busybox的include目录: ln -sf /usr/include/security security
接着make
又出错:

老办法，进入include目录:
ln -sf /usr/include/sepol sepol
要是系统没这个目录的话，呵呵，这个包的名字叫做libsepol1-dev,咋装不用说了吧
继续make
呵呵，链接出错，这是肯定的了，

这几个库交叉编译器可是没有的哦
没路了，要么交叉编译所需要的库，（痛苦的事情，我没成功），
要么重新配置下，去掉selinux和loging中的pam就OK了
make
ok,生成了
