limit-ordinal 85166bc706 Add NetBSD Support (#2661)
* 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
