The branch you mentioned is at least 2 years out of date. I recommend you use the current stable branch instead: https://gem5.googlesource.com/public/gem5/+/refs/heads/stable, which has all of the GPU support from the master-gcn3-staging branch (and many more) integrated into it. Moreover, to use the GPU model you need to have the ROCm stack installed, which it doesn't seem like you do based on your reply.
In terms of docker support, you may consider looking here: https://www.gem5.org/documentation/general_docs/gpu_models/GCN3. The website you listed is mostly about how to run the CPU models. I will note that the GCN3 documentation page does need to be updated though -- the stable branch now has support for GCN3 and more applications that square have been tested and released with it. We will work on updating this soon. Nevertheless, the instructions for the docker are correct and you should be able to use them to get an up-to-date version of gem5 that runs the GPU model running (the docker also has all the ROCm software installed correctly). Setting that all aside, I am not sure what version of gcc is used in Ubuntu 18, but there are some recent commits that updated gem5 to require gcc >= 7. If Ubuntu 18 uses an older gcc, I don't think it will work (using the docker should get around this though).
