It seems that you need to add `DISABLE_PCH_REUSE` to more cases to handle the incompatibilities. Refer to [iree-org at f474998](https://github.com/iree-org/llvm-project/commit/f474998fc35c1077911c3a2fbbcb4f5f7c283a71) for our fixes.

Instead of disabling pch for `-fPIE` executables, couldn’t you just add `-fPIC` to the flags?
