Description
After #5058 DPC++ build is failing during the cm-emu configure step. A temporary fix is to set sycl_build_pi_esimd_emulator = 'OFF' in llvm/buildbot/configure.py. This definitely affects the CUDA backend but may well affect other backends.
Output
[584/3182] Performing download step (git clone) for 'cm-emu'

Note: switching to 'c19234cea13bdfc32b5ed9'.
You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:
git switch -c <new-branch-name>
Or undo this operation with:
git switch -
Turn off this advice by setting config variable advice.detachedHead to false
HEAD is now at c19234c CM EMU Release, v2021-12-09 (#112)
