Extracted from #514.

This is needed for NetBSD to become a tier 1 target.

The example set by glibc can be followed.

I'm interested in picking this up, but will have some questions in the future.
For now: The glibc example uses tools/process_headers.zig, would a requirement for this include adding netbsd to this file as well?

We've decided that we're not going to support upstream static libc for the BSDs for two reasons:

  • It's a significant amount of C code we'd have to import (~17M for NetBSD).
  • BSD libcs are developed alongside the kernel, meaning whenever we import libc code, it's likely to contain subtle dependencies on the kernel from that same OS version. This makes static libc a strictly worse option for cross-compilation on BSDs.

Therefore, this issue is done as of #23913.

We're still open to exploring static libc for the BSDs, but it'll have to be by way of libzigc, i.e. #2879.
