We only want that for the standard Lua interpreter so that users do not
have to rebuild it every time they want a new library. Libraries can be
then distributed in binary form as a dynamic library and users do not
even have to have or know how to operate a C compiler (much less create
a dynamic library).
And, yes, for the standard Lua interpreter we strongly recommend
statically linking the core into it. (Unless you're in Windows, when you
need the core to be a DLL if you want to load user DLLs.)
