The choice of language for the installer in the GRUB menu
does not affect the language of the menu itself, which is strange.
Now Russian is selected without user prompt.

Image boot should be possible on a system without graphics

All distributions and starterkits switched from refind to grub-efi
a year ago. Sorry for not noticing that alt-server is still using
rEFInd.

These would have been lost as compared to 9.0 release otherwise,
and e2k's power button handling differs slightly so acpid is a must.

There was something wrong about that order of additives
and the base configuration; let's make it straight,
putting the foundation first and architecture-dependent
additions on top of it.

Note that double-colon syntax is specifically allowing
for multiple rules adding up their recipes (and prereqs),
but all of those rules must be specified as double-colon
(this was violated in the previous state of alt-server.mk).

This commit includes summary of the work done within RELENG-alt-server
branch, and goes over the existing bits regarding architecture support.

It was somewhat hard to keep separate so I finally chose to lump these
parts together.

Looks like aarch64 addition was done in haste,
the targets were split by architecture families
before commit c06f8753.

installer-feature-setup-plymouth needed make-initrd-plymouth.
make-initrd-plymouth missing for not X86 Arches in alt-server.
This resulted in a make-initrd error when installing on non-X86 Arches.

This parts reverts commit cff3291c.
Upstream mkimage has not yet take patches to support packaging
multiple kernels to ISO image. In order to avoid problems, have
to revert this commit.
