* Add NetBSD Support Includes: - Hints to find non-compatibility libc functions - Struct and constant definitions for sockets, polling, etc. - Changes to the linker code to work around some quirks in the NetBSD dynamic linker - A target triple for netbsd aarch64 so llvm builds/links the compiler properly on this platform * Updated releasenotes and some compacting --------- Co-authored-by: Christoffer Lerno <christoffer@aegik.com>
