The current depends installation instructions fail on bionic with
0E: Unable to locate package g++-4.8-aarch64-linux-gnu
1E: Unable to locate package gcc-4.8-aarch64-linux-gnu
2E: Unable to locate package g++-4.8-arm-linux-gnueabihf
3E: Unable to locate package gcc-4.8-arm-linux-gnueabihf
Also, they fail due to missing dependencies make automake cmake pkg-config python3
Fix this by removing the explicit version and splitting them into common instructions and instructions per linux architecture.
