path to jni.h broken

[GoogleCodeExporter]

linux systems often come with openjdk installed instead of sun-java. Thus
the correct java path could be  any one of
/usr/lib/jvm/java-6-openjdk/include/ or /usr/lib/jvm/java-6-sun/include.
The current configure scripts and makefiles assume the later resulting in
errors during make if you don't have the sun-java6-jdk package installed.
