While running a build for instrumenting for BOLT, I came across this build failure in openmp on LLVM/Clang-17 (7c2604ca196c3ba0247509c0fde350e23f0cccb0) when using Polly.
This is the script used for that specific stage that reproduces the issue.
[build_stage3-bolt-without-sampling.bash.txt](https://github.com/llvm/llvm-project/files/11832897/build_stage3-bolt-without-sampling.bash.txt)
One additional note, normally I don't use Polly in the script and could not reproduce the issue without the Polly flags.
