use defined instant of libc.so for initrd

[laijs]

don't use the host /lib64/libc.so

the build system should ensure every one creates the initrd with the same libs.

musl lib might be the best choice

+1, musl can also help to reduce the size of iptables binary.

What's the current status? Have you guys changed your mind? IIRC the current build script will copy more host lib into initrd.

just leave the issue for more days
