Well, the idea is as follows:
* LIB-OP collects all the .o files for your system in a .a
* DLL-OP collects all the .o files for your system in a .so

Now, on a C-based implementation, "all the .o files" means essentially
all your system, whereas on other implementations, it means only C
extensions that play the game (currently: none).

The idea is that you could always deliver a system (or a system +
dependencies) in either one file (.fasl) or two files (.fasl and .so),
depending on whether you're on ECL or another implementation.
