Woo thanks!
I have some comments, but I'm just being picky.

I know this is just copy pasted from above, but doesn't the indentation look odd?
Shouldn't the if/else/fi and the INSTALL_PROGRAM lines be indented with one tab
less?

Would it be good to put the part about gdb-add-index earlier in the page/section,
for example just after the first paragraph? The doc starts by telling you the
manual method with the scary objcopy lines and all. I think it would be nice if
it started by telling: here's the easy and recommended way, and then here are all
the gory details about how it's done internally, if you need it. I could imagine
users starting to read the section, and stopping midway because they think it's
too complicated/not worth it, and never get to the gdb-add-index part.
