i965/build: Add configure option to build i965_dri.so for a single Gen.single-i965-genexperiment/single-i965-gen
Allows the compiler to cut dead code and simplify when we know the
driver will run on a single platform. Perhaps useful for distributions
wanting to ship new hardware support without the risk involved in
updating Mesa for existing hardware.
