Install fixes, $prefix supported better, strip binaries and .so files

- Makefile fixes for installation, paths encoded wrong
- Strip binaries + .so files, support for $(CROSS) toolchain strip
- Default install is now to /sbin/finit and /usr/
- Use the 'plugindir' environemnt variable instead of 'PLUGIN_DIR'
