cannot build JVM support

[rkiddy]

I am trying to follow the directions at: https://uwsgi-docs.readthedocs.io/en/latest/JVM.html

I have installed uWSGI (I think) correctly, but I cannot see how to build the java plugin.

FYI, I am fairly new to and non-expert in uWSGI but have been around java for a while.

My full log is at: http://opencalaccess.org/misc/installing_uwsgi_java.txt
