GDB PATCH Fix lib/java.exp import of target_alias

lib/java.exp in the testsuite uses the target_alias variable without first 
importing it.  That gives a tcl error.  This patch fixes that (though it 
doesn't get the tests running for me, it seems that the compiles don't 
work if libjava isn't installed first).

OK?

R.

	* lib/java.exp (java_init): Import target_alias before using it.
