Well, as there is no way to update the Linuxcnc version, is there any other way to manually configure the INI and Hal to square the gantry using two motors and two sensors on the same axis?
 
Yes, you just need to set the home sequence to a negative number.

 I found a post by Rodw here on the forum where he says he has been using the sequence for a few years without any problems:

Joint_0 (x) - 1
Joint_1 (x2) - 1
Joint_2 (y) - 1
Joint_3 (z) - 0

Gantry homing has been a part of LinuxCNC since 2.8 IIRC. I would read the docs I linked for better information.

You don't need pncconf or stepconf to build a working config joint axes or not, you just need a text editor and do some reading. 
My Mesa 7i76e was not supported in pcconf so I had no choixe 7-8 years ago when 2.8 was relesed and I survived.
You could build a xyza config and edit the result

Yes, I'm working on it, I'm editing a configuration I made using stepconf and I'll test it on the machine as soon as possible. When you have tested it, I will return with the result whether it worked or not. Thank you for your help.

I managed to test it just now and every time I try to move an axis, a new warning like the one in the image appears.
 No engine moved...

You need to Home all before attempting to jog
If you don't have home switches, you will need to add them for a gantry as they are mandatory.
