Would you mind dumping whatever you do into a wiki page?

I'd love to have this semi-documented or at least in a state that we can
hand-wavy point people at when this requirement comes up.

I've been meaning to write up something like this because it's a common
practice we need to do for mechanical changes.

Likewise I've used readelf/nm and libabigail to do "no internal/external
ABI changes" between patches kind of testing, which I'll write up when
I get a free moment.
