As an aside, if anyone has heard anything about building GDB on an M1 Mac, I'd be grateful for a pointer. I'm asking because I'm currently stuck with lldb on my machine.  GDB doesn't seem to build - it doesn't produce an executable, but apparently, if I'm not blind, without saying what the problem is.
