[PATCH] D99620: [CMake][Compiler-rt] Fix `LLVM_MAIN_SRC_DIR` to be correct when `llvm-config` reports a path that doesn't exist.

[Tom Stellard via Phabricator via llvm-commits]

tstellar added a comment.

We still build compiler-rt in non-monorepo configuration for Fedora.  Which files from the llvm directory (or other directories in the monorepo) does compiler-rt depend on?
