"N" symbols and System.map

Hi all,

right now, we filter out symbols that nm tag N, meaning "debugging
symbols", from System.map. However, at least on x86, the
linker-generated symbol _end is tagged N, and in fact is the only N in
the entire image.

Are there other architectures which would suffer if N were included in
System.map, or would that be a reasonable thing to do?
