Lluís Batlle i Rossell 66d7126255 Take me (viric) out of most maintenance
Since years I'm not maintaining anything of the list below other
than some updates when I needed them for some reason. Other people
is doing that maintenance on my behalf so I better take me out but
for very few packages. Finally!

# TSAN requires XPC on Darwin, which we have no public/free source files for. We can depend on the Apple frameworks
# to get it, but they're unfree. Since LLVM is rather central to the stdenv, we patch out TSAN support so that Hydra
# can build this. If we didn't do it, basically the entire nixpkgs on Darwin would have an unfree dependency and we'd
# get no binary cache for the entire platform. If you really find yourself wanting the TSAN, make this controllable by
# a flag and turn the flag off during the stdenv build.
