Bug#338405: another patch for busybox support

[Russell Coker <russell@coker.com.au>]

The following will significantly reduce the size of an initramfs when busybox 
is used while also enabling all busybox commands (handy if you have an option 
to run a shell from the initramfs for recovery).  In spite of what maks 
thinks, the busybox option is still there, so it should be made to work well.
