Building in release mode with dub fails to link

[schveiguy]

I'm not sure what the problem is, but whenever I build with -release mode, and use ae as a dependency, it's failing to link with a slew of symbols in phobos and elsewhere.

I have a suspicion there is a weird dub configuration thing going on.

This is on Ubuntu Linux 20.04, with dmd 2.096.0
