(Over)thinking about this some more, I suggest using the empty string
for the start and "~" for the end. And, yes, I did check that ~ works
as part of a section name.

Something that confuses me is that gcc seems to give these sections the
"aw" attributes which makes as complain. This might be a gcc bug.
Worst case we have to use an assembly statement to create these
sections; it isn't a big deal and shouldn't make it any more
architecture-specific.
