 Simon, the branch has problems, as it turns out:
 {{{
   HC [stage 2] utils/ghctags/dist-install/build/Main.dyn_o
   HC [stage 2] utils/check-api-annotations/dist-install/build/Main.dyn_o
   HC [stage 2] utils/check-ppr/dist-install/build/Main.dyn_o
 epollControl: does not exist (No such file or directory)
 epollControl: does not exist (No such file or directory)
 epollControl: does not exist (No such file or directory)
 }}}

 I have sent the patch to `wip/T14677` and hopefully `circleci` will
 reproduce it.
