There are basicically two classes of cases:

1) Where the code is for obscure historical reasons or what I see as
misguided "optimization" split into a more libraries than necessary,
and these then are loaded at run-time. Instead, just use direct
linking.

2) Where dynamic loading is part of the functionality offered to some
upper (scripting etc) layer, or where some system-specific non-LO
library is loaded dynamically, as it is not necessarily present on
end-user machines. Can't have such in the DISABLE_DYNLOADING case.
