sumatra/graal build instructions

[Jules Gosnell]

Thanks for the heads up, Doychin,

interesting - I didn't notice any postings on either sumatra or 
graal-dev regarding this...

perhaps someone in the know would care to comment and clarify the situation.

specifically, I would like to know how this impacts the delivery of an 
HSA-enabled JVM and whether the HSA backend is continuing development 
elsewhere.

many thanks,


Jules
