You want to use mkinitramfs or mkinird or dracut or whatever your distro calls
it to create one.  gcc has no *clue* what needs to go in the initramfs (for
example, if your root file system is on a LVM partition on a LUKS-encrypted
disk, the initramfs has to do a 'cryptsetup openLuks' and then an 'lvm varyon'
before the mount will succeed).  Plus any modprobes that may or may not be
needed, etc etc etc.
