Yes, the --disable-sjlj-exceptions seems to be required. I wonder why 
it is not the default.
Also is --enable-threads=posix required? One would think that would be 
the default as well.
In any event, I get much further in the build now. My current problem 
is that it is trying to link the JNI alsa library against the build 
host's libraries. Bad Classpath, bad. :
