clang-compiled (incl llvm_ias and whatnot) linux/musl, running on 32-bit ppc for the first time ever
booting this was very funny because the usb stick does not appear in the OF device tree when put in the laptop's usb port, but does appear if you plug it into an old ibm keyboard hub that is plugged into the laptop usb port
but if you do that, it does not appear in linux and root does not get mounted, so you have to boot and quickly enough unplug the stick and put it in the normal port
