  To: igt-dev; +Cc: Petri Latvala

Compilation support was dropped in January 2019, since then it's just a
dead code in the repo and no one seems to be missing it.

Anyway, it can always be reintroduced from the chasms of git history.

-This tool is to be used to do shader debugging. It acts like a
-debug server accepting connections from debug clients such as
-mesa. The connections is made with unix domain sockets, and at some

-initiating connections with debug clients..
