  # Here we select the default bintools implementations to be used.  Note when
  # cross compiling these are used not for this stage but the *next* stage.
  # That is why we choose using this stage's target platform / next stage's
  # host platform.
  #
  # Because this is the *next* stages choice, it's a bit non-modular to put
  # here. In theory, bootstraping is supposed to not be a chain but at tree,
  # where each stage supports many "successor" stages, like multiple possible
  # futures. We don't have a better alternative, but with this downside in
  # mind, please be judicious when using this attribute. E.g. for building
  # things in *this* stage you should use probably `stdenv.cc.bintools` (from a
  # default or alternate `stdenv`), at build time, and try not to "force" a
  # specific bintools at runtime at all.
  #
  # In other words, try to only use this in wrappers, and only use those
  # wrappers from the next stage.
