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
* 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,
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.
