projectlibre is too slow on Baikal-T.

libreoffice-languagetool is not available on mipsel.

It's now uses just gtk3 and is available on most of the platforms.

It's used by many virtual environments, including PVE,
and was requested by one of the clients for alpha
Tavolga builds.

This package is not available with recent thunderbird.

They work better on Tavolga.

In addition to code re-use, it also pins chrony as
ntp daemon implementation, which helps to avoid
adding systemd-timesyncd into the images.

Available for mipsel too.

This is already done for VM_FSTYPE in a much better way.

There, DTB is named differently.

mipsel-bfk3 feature often serves as basis for special
build for various other BE-T1000-based devices. Having
DTB name in config.mk simplifies creating such derivatives.

To write rootfs images to flash.
