"-shared" and "-fPIC" are necessary to create a dynamically-loadable
object ("xxx.so") using gcc, which allows you to just load it into an
existing Lua executable.

You don't _need_ to do that, of course -- many programs just link the
C code and the Lua libraries when building normally.  In that case, you
don't need to use -shared/-fPIC.
