 https://gerrit.libreoffice.org/c/core/+/88917 and follow-ups.

 Since -Og was enabled for debug builds at one point in the 
past, --enable-optimized=debug could be also for those who are willing to try 
it for their builds. Seeing how much longer that makes things build here with 
Clang+PCH (+70% on starmath), I think I do not see it worth it myself.
