If it's impossible build the binary from the source you've been given, then you haven't been given the source. The binary in question is one that passes attestation and secure boot. If I don't have the key, I don't have the source.
MIT allows this (you not giving me the source). GPL2 allows this in some jurisdictions - notably, not in Germany. GPL3 absolutely doesn't, which is the reason Google refuses GPL3 upstreams.
