Needed for use one grub.cfg config for all grub platforms.

Directory syslinux can exist if using memtest feature.

It is required to set the BOOTLOADER and BOOT_TYPE variables in
grubpcboot.

Thanks for the idea Ivan A. Melnikov.

Needed for bluetooth support for Raspberry Pi.

This is necessary for the 'rootfs' initrd feature to work properly

This is a standard set of initrd features.

In make-initrd >= 2.5.0-alt1 feature usb requires kernel modules optional.

This features not needed for auto-detect.
We also add features not only to initrd.mk, but also specify them
explicitly in the command.

In menu you need the name of the distributiv.
If not set, then we will be as before.
Also corrected the selection of phrases for translation.

Needed for Raspberry Pi 4B 8 GB.

- deepin: add Network Manager applet
- engineering: initial as distributiv
- efi: fixed check modules for kernel-image >= 5.10
- oem: fixed calculation of required free space for installing additional
  packages
- oem: not use git in 60-oem-install.mk
- regular: do not default to mounting anything found (thanks mike@)
- rescue: added save session mode support for efi
- tar2fs: Disable os-probe at the time of grub installation
- xfce-sysv: add gnome-disks (suggested by Speccyfighter)

No problem with EFI support.

os-probe finds loopback devices.

It is not necessary to include u-boot for qemu as part of the
rootfs, since u-boot is started externally.

But with git might not work.

installer-feature-desktop-other-fs was made to ensure
that every filesystem available on the particular host
would be accessible upon installation; this is against
the regular builds and starterkits idea of "we give the
base, you do what *you* need upon it".
