Joseph Richey d2ca7695e3 Fix Solaris/OpenBSD/Dragonfly build and re-enable CI (#301)
Fixes #216 

This also adds two minor CI improvements:
  - Do a full link on `freebsd`
  - Build, Link, but don't run on `illumos`
  - Use the stable toolchain for our Tier 2 Build-only targets
  - Build (via `build-std`) for Tier 3 targets: `openbsd`, `dragonfly`, `haiku`
