This commit introduces a new optional makefile variable to let the build system know that, when running code, a custom QEMU binary must be used instead of the one provided by the system's PATH. Given that the CI machine won't keep up with QEMU updates unless its base image tracks a new version of QEMU itself, sometimes it is needed to use a custom QEMU build to be able to test new code in an emulated context rather than having to perform on-device testing during development.
