Comment (by thoughtpolice):

 The reason this is happening is because the `sync-all` script was changed
 to *properly* clone from GitHub (the original version I wrote was broke.)
 When you clone from your own fork, it attempts to rewrite submodule URLs
 to `github.com/tibbe/<repo>`. You probably don't have these repositories
 under your account, so it breaks because it can't clone them.

 IMO this isn't worth fixing, but perhaps explaining on the wiki - the more
 'correct' thing to do (which works) is just always clone/pull from
 `github.com/ghc/ghc` and set a remote to point to your forks.

 Of course I don't feel very strongly about this and if people want this
 behavior changed that's fine - but I feel I should point out it sort of
 didn't work before anyway.
