why scripts/link-vmlinux.sh has a final build of init/

Hi Masahiro-san,

 As I remember, init/ is already built during recursive make, and I did
a clean build(make mrproper, make localmodconfig) with all plugins
included on x86_64 with following patch, the kernel can boot without any
obvious problem. So, I don't figure out why we need this final build?
