This reverts 6d679eb2bcbe76e389c02e0bb4d4c4feb2847783 and additionally changes the command line parameters passed to Clang to match. Clang 14 defaults to DWARFv5 which is an interesting choice. v5 has been out for 5 years and yet Valgrind does not support it, and apparently neither does either GDB or LLD, I haven't determined which, but I wasn't able to use GDB to debug my LLVM-emitted dwarf 5 zig code that was linked with LLD. A couple years ago when I was working on the self-hosted ELF linker, I emitted DWARFv5 but then downgraded to v4 when I realized that third party tools were stuck in the past. Years later, they still are. Hopefully, Clang 14's bold move will inspire third party tools to get their shit together, however, in the meantime, everything's broken, so we're passing `-gdwarf-4` to clang and instructing LLVM to emit DWARFv4. Note that Zig's std.debug code *does* support DWARFv5 already as of a previous commit that I made today.

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.
