Why not just make it ".discard.unreachable", and then make the discard
pattern be ".discard*".
We already have .discard.text for some trace hackery, so it follows a pattern.
And that's what we do for things like .rodata.* etc.
In fact, we already have a pattern for '.discard.*' in the main
vmlinux.lds.h file exactly for the .discard.text case (but not for
modules, it looks like).
