[Libreoffice] bug in Jar_ScriptProviderForJava.mk?

[Tor Lillqvist]

I ran into the same problem today, and I think I fixed it by using a
variable called T_CP instead of CLASSPATH in gbuild to collect the -cp
option to be passed to javac. (Which is cleaner, too, as  the Java
CLASSPATH  concept and the -cp option to the Java compiler are
different things.) Pushed to master. I have no idea why this helps,
and why this problem was seen only on Windows...
