I was just reading about a linker option (--as-needed or something like
that) that exists in more recent versions of the GNU linker. It means
"only link the libraries actually referenced". Applying this or local
equivalent where available would seem like a fairly painless way to
solve the problem, at least on some platforms.

I agree that trying to keep track of the set of libraries really needed
for each executable would be a hopeless task, but if we can make the
linker fix it for us ...
