Thanks. configure now displays

  checking for library containing tputs... -ltinfo

But I still get a link error, due to configure.ac line 6062. I needed
to change this line
  mingw32 | android)
to
  mingw32)
in order for the build to go further.

With this done, "make" succeeds, and "make install" works fine as well.
If there are issues with "make check", I'll report them separately.

Good point. Indeed, if config.guess guessed it correctly, my mistake
yesterday would not have happened.

For such tiny contributions to config.guess, no copyright assignment is needed,
per <https://www.gnu.org/prep/maintain/html_node/Legally-Significant.html>.
I filed a patch here now:
