This is sufficient to build a stdenv on Darwin. Note that it requires reverting fb777be, which is already reverted in staging (e560459).

staging-next has a ugly work-around which effectively reverts that commit.

@pbogdan could you take on the role of CI once more? 😄

@kampka should the revert be added to this PR?

@FRidh imo it would make sense. Added the revert commit to the PR.

LGTM, I had a texinfo 6.7 + gettext change in a local tree (along with the build artifacts), double checked and nix-build -A stdenv and nix-build -A texinfo succeed on this branch.

Just let me know if there are any further changes to test.

allegro was still using the 6.5, now nixpkgs is broken on staging:

if this is in staging-next, then it will have broken hydra
