This might be the desired use case, but when cross compiling with systems like
buildroot one might have the same architecture on --build and --host.

Example: Compile on Apple silicon (aarch64-unknown-linux-gnu) for a Cortex A75
based system (aarch64-unknown-linux-gnu). Cross compiling isn't automatically
detected.
And there seems to be no way to force it if we know that we are cross
compiling.
