Build error: libtinfo.so.5 not found

I'm getting the following error when running make build to build Raspberry Pi targets:

$ make build

What should I do?

You should install libtinfo5, for instance on Ubuntu 20.04:

$ sudo apt install libtinfo5

This won't work out of the box because the default version installed with the OS is libtinfo6, so we have to install the extra dependency manually here.
