Thanks for this example. We can actually use codesearch to get a crude
idea of the prevalence of this:

  https://codesearch.debian.net/search?q=path%3Adebian%2Frules+%5C-Wl%2C%5C-%5C-as-needed&literal=0

Any input on whether a brute grep for "-Wl,--as-needed" in debian/
rules would be sufficient to catch most instances of these? (Feel free
to drop moreinfo tag upon replying.)
