Looks like the logic is reversed here. This flag seems to enable the old glibc.

This should be manual: True, right? We don't want the dep solver trying to change this flag.

It would be nice to have some kind of a changelog entry explaining this change and what the impact of enabling the flag would be.

On Mac OSX, with an old XCode and glibc, unliftio doesn't compile :( ( #59 ).
I've tried adding a build flag around the problem but I can't get it to propagate down to GCC.
I understand supporting old systems might not be high in priority but I figured a change along these lines would be minimally disruptive (and allow me to use unliftio on my janky old laptop!)
Looking forward to all feedback.
