The curious thing is that I added that line not too long ago to fix a crash on the smartphone/Monado version. I think we should control this using a cargo feature flag, and expose that from xtask too.

Can you link to the issue ? we can control it that way, but it really has c++static stdlib already in it, and it shouldn't ask for a new lib

Added shared stdlibc++ linking as a feature as suggested :)

Since this PR does not integrate with xtask to conditionally add the flag, it essentially disables it completely. I tested this on my Quest Pro and it works still. I think we can merge this and fix Monado compatibility another time.
