Well, a cpio archive can be generated by Buildroot without having to
build a kernel, see fs/cpio/Config.in. What Grant was complaining about
originally was the fs/initramfs case. However, last time I tried
pointing CONFIG_INITRAMFS_SOURCE to a cpio archive, it didn't work.

Instead of my original solution, another solution would be to *not*
make initramfs depend on BR2_LINUX_KERNEL, and to remove the dependency
initramfs->kernel so that the kernel doesn't try to be built as soon as
initramfs is selected. If kernel is selected, it will anyway be built
*before* going through the initramfs code.

Would this be ok ?
