Link error on macOS 10.12.6 about pathfinder

[rpjohnst]

This also happens on Windows. It looks like the reference tests just haven't been implemented for every platform yet.

[pcwalton]

The solution is going to be to make these dependencies opt-in.

I tried to workaround the first linker error by running brew install freetype, which worked. The next error was:

   Compiling pathfinder_server v0.1.0 (file:///Users/john/Development/pathfinder/demo/server)
error: linking with `cc` failed: exit code: 1

Solved with brew install librsvg. Then a similar error but for -latk-1.0 -- brew install atk. Then a similar error but for -lgdk-3, at which point I gave up.

[pcwalton]

I believe this should be fixed now by making those dependencies opt-in, but because of the nature of this bug I can't be sure. Please feel free to reopen if you still see any issues.
