Merge pull request !55 from Harylee/mem

背景：内存调测模块编译时依赖libunwind.a库，编译时若不显式指定-lunwind链接选项对于依赖该库的程序
会编译报错。
修复：由于对链接libc.a库的所有程序添加对应的链接选项不现实，故将libunwind.a打包进libc.a，使得依
赖libunwind.a的所有程序无需显式链接unwind库即可链接成功。

the //kernel/linux-4.19 kernel is not the final codes used to
generate linux kernel image, it is patched before compile.
so we should use the patched kernel source to generate uapi
header files.
