There should only be one compiler per architecture. Those cases where the same compiler can deal with a different architecture should be explicitly set for both cross_cc and docker configurations. Otherwise you get strangeness like: --cross-cc-aarch64=/bin/false causing the logic to attempt to use a locally available arm-linux-gnueabihf-gcc rather than forcing the use of the docker image which is what is implied by the command line option.
