sumatra/graal build instructions

[Doychin Bondzhev]

Hi,

Few weeks back there was a change set that removed all HSAIL and PTX 
specific code from graal. I don't know what that means but I suspect 
that graal won't support GPU code for now.

This also leaves sumatra future unknown for the moment unles someone 
with more knowledge provides us with more information.

Have a nice day,
