linking demos

[Gaius Mulley]

Hello,

here are some demo videos about the linking changes to gm2:

   https://www.youtube.com/watch?v=d9zxZdxVq-k   Part 1 Linking hello world
   https://www.youtube.com/watch?v=CedR710hc5s   Part 2 Tracing module 
initialisation
   https://www.youtube.com/watch?v=8m13yPa02gY   Part 3 Linking a shared library

I suspect much of the content will be very obvious, but there are some
subtle changes (for example the ability to link a modulename.o with the
gm2 driver, the scaffold flags and the runtime environment variable).
Anyway maybe they are of some use?

regards,
Gaius
