Thanks for the report.

I'm more interested in why configuring for your cross-compilation
environment doesn't find any of the curses libraries or headers. Do
you have them installed?

What does config.log say about searching for the curses and termcap
libraries?

The ancient termcap library bash includes is the bare minimum to get
a successful link.
