Previously, when choosing the local cache directory, if there was no root source file, an explicitly chosen path, or other clues, zig would choose cwd + zig-cache/ as the local cache directory. This can be problematic if Zig is invoked with the CWD set to a read-only directory, or a directory unrelated to the actual source files being compiled. In the real world, we see this when using `zig cc` with CGo, which for some reason changes the current working directory to the read-only go standard library path before running the C compiler. This commit conservatively chooses to use the global cache directory as the local cache directory when there is no other reasonable choice, and no longer will rely on the cwd path to choose a local cache directory. As a reminder, the --cache-dir CLI flag and ZIG_LOCAL_CACHE_DIR environment variable are available for overriding the decision. For the zig build system, it will always choose the directory that build.zig is + zig-cache/. Closes #7342

The ultimate goal of the Zig project is to serve users. As a first-order effect, this means users of the compiler, helping programmers to write better software. Even more important, however, are the end-users.
Zig is intended to be used to help end-users accomplish their goals. Zig should be used to empower end-users, never to exploit them financially, or to limit their freedom to interact with hardware or software in any way.
However, such problems are best solved with social norms, not with software licenses. Any attempt to complicate the software license of Zig would risk compromising the value Zig provides.
Therefore, Zig is available under the MIT (Expat) License, and comes with a humble request: use it to make software better serve the needs of end-users.
This project redistributes code from other projects, some of which have other licenses besides MIT. Such licenses are generally similar to the MIT license for practical purposes. See the subdirectories and files inside lib/ for more details.
