Cross compilation fixes for the stargates, 'gmake client' should now build, link, and install properly. Haven't really tried to run stuff though. * GNUmakerules: Add target for stripping executables, used instead of "install -s" since that doesn't work for cross-compiling. * Makeconf.in: Add ELVIN_CONFIG variable that refers to 'elvin-config'. * configure, configure.in: Detect and save the elvin-config path since we need a different one for cross-compiling. * event/lib/GNUmakefile.in, event/link-agent/GNUmakefile.in, event/linktest/GNUmakefile.in, event/program-agent/GNUmakefile.in, event/proxy/GNUmakefile.in, event/tbgen/GNUmakefile.in, event/trafgen/GNUmakefile.in, os/dijkstra/GNUmakefile.in, os/syncd/GNUmakefile.in, sensors/slothd/GNUmakefile.in, tmcd/GNUmakefile.in, tmcd/linux/GNUmakefile.in: Cross compilation fixes, don't statically link on arm, create "foo-debug" executables with debugging info and install separately stripped ones instead of passing "-s" to install.
