No, I can’t compile the 32bit bins myself as they are closed source. The point is really that it would be great if buildroot could be setup to support 64bit compilation (aarch64) with multiarch support so that 32bit libraries (libc, etc.) are automatically in place that 32bit binaries (armhf) will run out-of-the-box. Does anyone know how much effort it would take to add such multiarch support into buildroot and where to start implementing it in a nice and proper way?
