Thanks. I also determined after the fact that universalsdk was the
problem, but I didn't know how to fix it. Unfortunately, it turns out
what you identified was a transcription error on my part - I had been
using --enable-universalsdk instead of --enable-universalsdk=/.
Thanks for the help, I appreciate it!
