Need whole archive on examples/app on Linux.

[georgemorgan]

The app.a file needs to be wrapped with -whole-archive and -no-whole-archive.

I can't remember if this still needs to happen. Can you test this, @nicholastmosher?

I don't remember the context of this. What does it mean to have -whole-archive or -no-whole-archive? What is it that I would be testing?
