[ptxdist] [PATCH v2 1/2] classpath: Fix for building with OpenJDK-1.8 (again)

["Guillermo Rodríguez" <guille.rodriguez@gmail.com>]

Commit bbc978e623cafc added a patch intended to fix building
with OpenJDK 1.8, however that commit was not complete. Update
-source/-target in Makefiles and run autogen.sh so that the
configure script is regenerated and the patched m4 macros are
used.
