you can use the Command() method (see http://www.scons.org/doc/production/HTML/scons-user.html#chap-builders-commands ) to run 
single commands like this one. However, if you need this functionality more often you should consider to write a proper Builder for 
creating loadable Kernel modules (see http://www.scons.org/wiki/ToolsForFools ).
The Command() should look something like this:

   env.Command('foobar.o', ['foo.o', 'bar.o'], '$LD -r $SOURCES $TARGET')
