* Don't link against pthreads. This was added way back in r211 

because Berkeley DB needed it on some platforms, but we don't use
  BDB anymore.

  On FreeBSD, if you link against pthreads, then the main thread gets
  a 2 MB stack which cannot be overriden (it ignores "ulimit -s"):

  This is not enough for Nix.  For instance, the garbage collector can
  fail if there is a pathologically deep chain of references
  (http://hydra.nixos.org/build/556199).  2 MB is also not enough for
  many Nix expressions.
  
  Arguably the garbage collector shouldn't use recursion, because in
  NixOS unprivileged users can DOS the garbage collector by creating a
  sufficiently deeply nested chain of references.  But getting rid of
  recursion is a bit harder.
