v2.2.0

What's New

• zig sdk: bump to 0.12.0-dev.2127+fcc0c5ddc in #140 and #141

Zig upgrade brings in the following changes:

• bump glibc support from 2.34 to 2.38
• fix integration with some glibc symbols: ziglang/zig#17702
• mitigat error: AccessDenied, which, according to Noah Santschi-Cooney, also mitigates/fixes the dreaded error: FileNotFound which we sometimes see when setting up Bazel worksace. Relevant commit in Zig: ziglang/zig@6b27096
• linker: support --(no-)undefined-version: ziglang/zig#18486. This will unbreak some Rust users.
• LLVM16 -> LLVM17, which now defaults to -Wl,--undefined-version, which can result in failure to link some C code (but easy to mitigate). Example in zlib and the specific workaround.
