How do you create a shared object?

To create a shared object suitable for linking against:

1. Compile the source files for the library using the -shared option to qcc.
2. To create the library from the individual object modules, simply combine them with the linker (this is done via the qcc compiler driver as well, also using the -shared command-line option).
