In certain configurations, libc++ headers all exist in the same directory, and
libc++ binaries exist in the same directory as lldb libs. When
`LLVM_ENABLE_PER_TARGET_RUNTIME_DIR` is enabled (*and* the host is not Apple,
which is why I assume this wasn't caught by others?), this is not the case:
most headers will exist in the usual `include/c++/v1` directory, but
`__config_site` exists in `include/$TRIPLE/c++/v1`. Likewise, the libc++.so
binary exists in `lib/$TRIPLE/`, not `lib/` (where LLDB libraries reside).
The `LIBCXX_` cmake config is borrowed from `libcxx/CMakeLists.txt`. I could
not figure out a way to share the cmake config; ideally we would reuse the same
config instead of copy/paste.
