Hm. Ok. Thanks for the heads up.
I can restore the flag for htl/pthread easily enough.
I'm less certain how to do this properly conditionaly for anl but I'll
look into it. Possibly I'll just restore the flag for libanl (see below).

It's harmless for a stub library to have the flag if it doesn't need it,
so I'll probably leave librt tagged until it's fully merged (unless it's
easy to to do conditionally given the current setup).
Not worth introducing a ton of complexity into the build system for imo.
