This will allow in the future to use a different initrd option when
building images, for example dracut.
Also drop old make-inird support.

the * symbol was seen as a symbol because of the options in the shebang.

In the future, it is planned building iso without propagator.

the variable was renamed earlier. See: sub.in/stage1/Makefile.

At the moment, the ability to select the kernel with which to boot is
implemented only for grub (grub-pc, grub-efi, ieee1275boot).
note that renamed STAGE1_KFLAVOUR to STAGE1_KFLAVOURS, as multiple
kernels can now be added.

This reverts commit 5848ae70.

QEMU for riscv virt machine passes its own DTB. Overriding DTB breaks
Linux loading.

ttySI0 was a name of HiFive Unleashed serial console. It was changed to
ttySIF0.

The intention behind this commit to allow user to get all needed stuff
to launch a particular image inside QEMU without need to download the
firmware from the net or in a case of booting procedure change in
future.
