And even for boards that do, -g is the right thing to do. If you don’t
want debugging symbols, strip the binary, but it’s useful to default to
including them; distributions generally do exactly that, stripping the
installed binary but keeping the debug symbols around in a separate
.debug file.

Debug symbols also aren’t loaded into memory, they only exist on disk,
so the only cost is a bit of disk space.
