Grep the whole build log for error messages, there should be something
additional. This is an error that happens when cbindgen fails to do
something with the C++ compiler.
Firefox is known to not build on NetBSD-8 due to C++ templating errors,
so that will most likely be the error.

We should mark it as NOT_FOR_PLATFORM until we have a solution for this.
It is turning into a FAQ.
