Use the values from Makeconf to find java (Unix), falling back to JAVA_HOME (which is needed on Windows). Add the directory to PATH on Windows or dyn.load the shared library it on Linux. macOS is kept largely the same as it was except we check Makeconf before JAVA_HOME.

This is not the way to go - have a look at https://github.com/s-u/rJava/tree/feature/dynamic which is likely the path forward if we also want dynamic loading on Linux.

LD_LIBRARY_PATHand also want to have as dynamic a Java configuration as possible (various Java implementations are available). On Windows we augment PATH before attempting to load the rJava DLL.Use the values from Makeconf to find java (Unix), falling back to JAVA_HOME (which is needed on Windows).

I hope this doesn't break lot of other things and that the approach is acceptable. I should state, I'm not much of an R programmer and so would welcome any and all feedback.
