There are several options here but none of them are really awesome: The short answer is you board is generally not fully supported for mining but should be eventually.
Even though the open source Radeon drivers in 16.04 are supposed to support the Tahiti SI boards, they do not bring with them OpenCL 1.2 support which is required for Ethminer. I realize this is a bit old but I have just developed some good experience with this issue so I thought I would share my knowledge.
