And I mentioned exactly this. It's my third alternative.

And it doesn't work well, exactly because developers don't know if the
libraries they use are always single-threaded etc. More importantly, it
just doesn't happen that much. People do "make ; make install". Hopefully
from pretty standard sources. Having to tweak things so that a project
compiles with a magic flag on a particular distribution is simply not done
very much.
