JNI library files have different locations on Fedora/EPEL and Debian:
- support different locations without patching the upstream code
- update packaging according to the guidelines (http://fedoraproject.org/wiki/Packaging:Java#Packaging_JAR_files_that_use_JNI, http://www.debian.org/doc/packaging-manuals/java-policy/x104.html), new Debian subpackage libglite-lb-client-jni
- ldconfig command not needed anymore
Support build of java client on Fedora (use axis1.4 prefix from EMI 3rd party repository only for EPEL).
