Well-adapted interface for a small smartphone screen.

Add apps tested to work more or less nice on mobile interface.

Thanks @thatman (Alexander Burmatov) for testing.

These targets do not have a network subsystem defined, so it was
not to add a target use/net-ssh.

At the moment this target is focused exclusively on make-initrd,
but some weird kernels don't have a dependency on mkinitrd.
It's loongarch64 again.

glibc can be compiled such that mki-fake-dev requires /proc to works.
This on loongarch64.

This script was left after phosh background config moved to /etc/skel.
Having ~/.config touched broke /etc/skel copying onto user homedir.

Now vm/regular-cnc-rt is universal. Bootloads on both Legacy BIOS
and UEFI (x86_64).

In new kernels cifs.ko is now there.

openvm-tools required systemd.
But extended virtual machines support doesn't seem necessary for
regular builds with sysvinit.

This will boot on u-boot with extlinux.conf and on edk2 with grub-efi.

Fix build on x86_64.

Both UEFI and Legacy BIOS are supported on x86_64 machines. Now the
image x86_64 will be bootloaded on both.

grub-efi-autoupdate does not update grub in EFI/BOOT if there is
no shim and EFI/altlinux.
See https://bugzilla.altlinux.org/41959

Fix the build for platforms where there is no un-def.

This will start phosh with the screen locked. When the user unlocks
the screen, he is fully authorized. Without it, many applications
do not start.

This reverts commit 4a405aed.
It's too early to switch to it.

This will fix /home/altlinux directory owner with 'root' to 'altlinux'.

Now is not problem with serial console.

Dropped out of image gnome-control-center and xdg-desktop-portal-gtk
because fix ALT bug 46895. Add them.
Also now phosh requires mutter-gnome and gnome-shell-data  because
fix ALT bug  46896.

Removed from Sisyphus.

Needed make-initrd-bootchain >= 0.1.5-alt18
