I am not sure if this is a bug or just my own fault, but I can't crosscompile for a raspberry pi when midir is a dependency (it works just fine if I comment it out in Cargo.toml).
The problem seems to happen at the linker stage (warning, really long!):

I managed to compile the same thing directly on the target hardware, but it takes forever and speeding it up would be really convinient. Any ideas?
