Subject: [PATCH] tbb: clean up
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Drop compiler and stdver arguments – if someone needs to provide them, they can just use overrideAttrs
- Update repo source
- Narrow scope of `with lib` declaration
- Change optional → optionals
- Use one input per line
- Build on all unix platforms
- Re-order attributes
