If building using a bootstrapping configuration (`-DLLVM_ENABLE_RUNTIMES=flang-rt`, implicitly added when `-DLLVM_ENABLE_PROJECTS=flang`), the mod files are automatically put into the Clang/Flang resource directory as a dependency of `check-flang`. If explictly disabled using `-DFLANG_ENABLE_FLANG_RT=OFF` or in a Flang-standalone build (that currently does not support LLVM_ENABLE_RUNTIMES), Flang-RT can be compiled separately and `FLANG_INTRINSIC_MODULES_DIR` pointed to it. `lit.cfg.py` will add the path via `-fintrinsic-module-path` to each `flang`/`%flang_fc1` call. If FLANG_INTRINSIC_MODULES_DIR is not set then tests in `test/` will be skipped.
