The existing logic does not work as it is breaking bootstrap on
Linux/Ubuntu as presented here:

Why do you need terminfo/termios in ./build.sh tools?

We need to fix bootstrap on Linux and it is easier to remove terminfo
features and termios ones. We don't need to handle terminal resizing
detection or colors for tools.

Instead of supporting these features dynamically it is easier to disable
them unconditionally. But if you insist to detect them dynamically and
maintain it, please land a patch that will resurrect the bot.
