Is it still possible to compile LibreOffice 24 for Linux 32-bit?

There is no upstream proactive 32bit testing since longer before that 
baseline bump. (Stuff I report once in a while get fixed, though, usually).

Debian still ships LibreOffice on 32bit archs, as do other distributions.

But it's slowly dying, yes....

All correct. I do -g1 in Debian. LTO works.

And because of exactly this case I (also) don't use --enable-mergelibs 
on 32bit architectures.
