right now, we filter out symbols that nm tag N, meaning "debugging

Are there other architectures which would suffer if N were included in
System.map, or would that be a reasonable thing to do?
There should not be any N symbols unless you are using stabs debugging.
We have in vmlinux:
.end : AT(ADDR(.end) - LOAD_OFFSET) {
_end = .;
}
And I see:
c1834000 N _end
This is the _only_ 'N' symbol in my vmlinux.
Yup, this is what happens. I don't know why the linker does this, and
if there is a way around it.
