Band-aid fix to stop race conditions in llvm errors
This is a big hammer, but should be effective at completely removing a few issues, including inconsistent error messages and segfaults when LLVM workers race to report results LLVM_THREAD_LOCAL has been present in LLVM since 8 months before 3.7 (the earliest supported LLVM version that Rust can use) Maybe fixes #43402 (third time lucky?)
