I talked with our lawyer, and we determined that GCC's technique of
checking for a symbol whose name says "I am under a GPL3-compatible
license" is ok for Emacs and other GNU packages when dynamically
loading libraries at the C level.
So you can implement dynamic loading with the check for that symbol.
If the symbol is not present then the function to load should
report an error and not load it.

That's great news. So all we need now is for someone to submit a patch
that provides such dynamic loading functionality, and then start
using it.
