stage2 build fails

[Simon Peyton Jones]

  git clean -dfxq && git submodule foreach git clean -dfxq

That made it work! Thank you.

(Of course I have no idea *what* file 'make maintainer-clean' isn't removing, but maybe we should not worry over-much.)

|  I ran into a similar(?) problem a while ago. "make maintainer-clean"
|  does not necessarily remove every generated file. See for example

|  Since then I only use
|  
|    git clean -dfxq && git submodule foreach git clean -dfxq
|  
|  which worked reliably for me (beware that this removes any untracked
|  file). Maybe this helps?
|  
|  Cheers,
