I got a little more familiar with how Zig compiles things! Looks like this is because we don't package a libc for FreeBSD; accordingly, it's not in available_libcs, and one way or another we end up returning an empty libc_include_dir_list here.

It works fine if you build on a FreeBSD host with this command:

CMAKE_GENERATOR=Ninja ./build x86_64-native baseline

however, zig does not have the ability to cross-compile for this target yet.
