The port is good enough to be able to successfully link the whole Zig compiler and its test suite.
This set of patches is part of my effort to let it build and run a whole Zig program that's dynamically linked against glibc, I'm progressively fixing lld as needed.

My current roadmap is:

- Implement the remaining TLS models {IE, GD, LD}
- Implement the `GOTDATA` relocations.

Some fixup commits to fix what was broken/missing are perhaps inelegant but necessary.
