Add detection logic for missing OpenSSL symlinks on macOS (dotnet#986)
Browse files Browse the repository at this point in the history 
By far our most common EE error is due to folks not having the OpenSSL symlinks created. This checkin adds detection logic so that we will not install the debugger unless they are present.

This resolves dotnet#779
