Use `VFS.equivalent()`, which follows symlinks, to check if two module cache paths are equivalent. This prevents a PCH error when building from a different path that is a symlink of the original. ``` error: PCH was compiled with module cache path '/home/foo/blah/ModuleCache/2IBP1TNT8OR8D', but the path is currently '/data/users/foo/blah/ModuleCache/2IBP1TNT8OR8D' 1 error generated. ```
