Understood (and sorry for the bad tagging).

GOOD news! It works, it works, it works! :-D

This bug can be closed (not a bug or whatever you prefer).

Reason: no need for wishing for a feature that is already present. 

Confirming Rene's statements, Debian's LibreOffice packages (26.2.x) are
using a different baseline than LO's one and thus, not applying/showing 
the upstream packages restrictions/limitations, at least the one for the
need of a «modern» CPU.

1. Proof of working / what I have done:

On my usual «oldie» (ahem) testing system, running Debian testing 
flavor, I have installed Sid (unstable) LibreOffice packages 
(now 26.2.0.3) and these packages are running and launching LO as 
expected.

2. Info / details:

Should additional information / tests are required just ask.

Just a final «wish» to LO package maintainers: keep this compilation 
options as much as you can to avoid premature / planned obsolescence!

Cheers,
