BUILD_JOBJC woes on Mac

[Erik Joelsson]

In the old build, JObjC.jar was built completely differently from all 
other java classes, by an ant script. We kept the source/target 1.5 when 
converting to the new build to keep the builds equal. I very much doubt 
there is a reason for it now though. It looks like left over legacy to me.

The simplest fix for you would be to change the outputdir of the 
generated sources for jobjc to something like gensrc_jobjc.

I would really like to see the whole special handling of jobjc 
compilation removed.
