Haven't thought about make since about 1993 and my exposure then was
minimal.  Remember "make"; not "install".

Thanks.  Was oblivious to that.  "man make" gives no mention of install but
TLDP helps.

etc.

Found it about a week ago.
https://wiki.gentoo.org/wiki/Utelnetd
https://boxmatrix.info/wiki/Property:utelnetd
https://public.pengutronix.de/software/utelnetd/
https://sourceforge.net/projects/utelnetd/
The boxmatrix and pengutronix pages suggest that it was developed
primarily to allow a console on an embedded system.

You should look into Secure Shell SSH instead of telnet. SSH encrypts the traffic but telnet is plain  text. SSHD is packaged and available on Debian.

If all else fails, may ask another question.

Used it for years.  When multiple terminals connected to a central
mainframe it was appropriate.  My application is software (embedded)
in a Debian system.  Only 2 or 3 telnet consoles needed.

Gruesome details here.

inetd/telnetd is rather overkill and utelned should suffice.
