I have the same problem but in Windows 7. My Segger output looks like this:

Thanks for updating with this! Feel free to also accept your own answer, if it is useful!

I love answering my own questions.

I took a chance at trying the "Standard GDB Hardware Debugging Launcher" instead of the "GDB (DSF) Hardware Debugging Launcher" that NAN-29 suggests. This is a little bit of fine print at the bottom of the "Main" tab in the debug configuration editor. You have to override the default.

And voila, it works within eclipse, and seemingly quite well. I'm only debugging blinky right now; I'll take on a real BLE sample next, but I am no longer slowly going insane trying random settings.

I hope this helps any of you out there trying to use your mac for development.

Update: running gdb locally, connecting to the JLink GDB server, seems to work quite robustly. An ugly way to debug, but maybe better than nothing.

I'm running the same gdb from the command line that I am telling eclipse to use, with the same commands in the startup script. Suspicious. Timing maybe?
