[java] Fix detection of gcj when building with newlib

[Richard Earnshaw]

This patch fixes detection of the gcj program when building with newlib.  
Without this patch builddotdot is not initialized and configure ends up 
trying to use a previously installed version of gcj (if such a tool 
exists).

	* configure.in: Fix detection of gcj when building with newlib.
	* configure: Regenerated.
