Currently, my understanding is that the sanitizer runtimes look for an external symbolizer with `ASAN_SYMBOLIZER_PATH` (or `UBSAN_...`, ... depending on the sanitizer), and if it isn't found looks for `llvm-symbolizer` binary in the `PATH`.
It would be nice to teach it to look for `LLVM_SYMBOLIZER_PATH` environment variable after the sanitizer-specific environment variable and prior to looking in the `PATH`. Lots of systems seem to spend quite a bit of time basically replicating the path of the symbolizer binary across N different environment variables because this is missing, including Lit for example.
