[Vm-dev] new display driver for Syllable

[Kelly Wilson]

Hey everyone,

I managed to figure this out. It seems that the vm-display-custom.la file
was not being properly output because of some Syllable weirdness. The -lSDL
library also wasn't being include correctly for the dynamic lib when being
built.

Anyways, I just looked at what Linux was doing and tried to build the custom
display by hand...this worked.

Thanks,
K.Wilson

P.S. I am sure other problems will pop up...I will post when appropriate.
