Obviously.  I'm equally obviously referring to klibc, which was designed 
so that the resulting vmlinux/bzImage/... file contains the necessary 
initramfs, regardless of issues like cross-compilation, draconian size 
restrictions(*), and so forth.

(*) Not saying that a klibc-based initramfs is necessarily smaller than 
the in-kernel code it replaces, but the total size is << than the size 
of the kernel proper, which isn't true when using a full-featured libc.
