I'm surprised by the different behavior between Fedora 40 and Ubuntu 24.04
with the Build from Source process.  While on F40 you get a warning,
everything installs. But on Ubuntu 24.04 the sudo make install fails. You
can get around it with the --break-system-packages option in the Makefile
in the binding directory or use it as an Environment variable.  F40 must
have different rules on this than Ubuntu.

While I would not normally build mythtv from source on Ubuntu since the PPA
has all the packaging done for you and it just works, I am trying to
understand if Build from Source is out of date or if the automated Ubuntu
package builder uses different building instructions.

The break-system-packages override scares me a little, but if it's what the
system packagers are doing maybe the Build from Source Wiki needs to
include that override??
