makeJava again

[Pavel Roskin]

Hello!

I have corrected makeJava script in such way that it doesn't use "test"
command for timestamp comparision.
Now even /usr/old/bin/sh on HP-UX can run it.
Maybe some other changes will be needed, for example setting of default
srcdir (however it may be convenient to call makeJava from make and set
srcdir through the command line).
Of course, this script doesn't ensure that everything is rebuilt 
correctly, but I don't want to rebuild everything after I change two lines
in AppletViewer.
