Conditional compilation of jimi, jai, and jce was not working properly. Each had separate compile jobs, but was also included in the main source

compilation, which resulted in compile errors. This change removes the
separate compile jobs, and excludes them from the main compilation bases
on the previously existing conditional tests. Also added a message showing
the results of these tests as they are performed (eg. "Jimi Support NOT
Present").
