the link step gets -lncursesw added, it still is not able to find the =
symbol:

Okay, this is because recently on -CURRENT, libtinfow got split off from
libncursesw: https://cgit.freebsd.org/src/commit/?id=3D396851c20aebd

This affects such cross-builds obviously, and manually adding -ltinfow
to the link command line makes it link correctly.

However, the 396851c20aebd commit is probably not suitable for MFC'ing
to stable/13. Maybe we need to put some kind of kludge in
share/mk/src.libnames.mk for this, or in the top-level Makefile.inc1?

Baptiste, any ideas? :)
