Sure, but I'm thinking it also might be a piece of the bootstrap puzzle
that we don't (or shouldn't) need to worry about.

How's this patch look?  The various macros seem undocumented, but this
looks like what the various test linkers are using.

(yes, I know it won't apply cleanly, it's part of a bigger mess I'm
working with ;)
