This is necessary for hurd, and the bulk from misc/terminfo.src is also
built that way.

And not only those; to see the whole story, it is necessary to run
infocmp with the -x option:
,----
| $ mkdir -p /tmp/terminfo
| $ infocmp xterm > /tmp/foo
| $ TERMINFO=/tmp/terminfo tic foo
| $ infocmp -x -A /lib/terminfo -B /tmp/terminfo xterm xterm

The relevant capability here is kUP; removing it fixes the Emacs problem
for me.

I'd like to get a comment from Thomas (CC'ed) before doing anything.
Thanks for the report.
