It's because libgcc appears in the wrong place in the command line, and
due to the way kbuild works, we can't get it into the right place easily.
Linkers are sensitive to the order of archives on the command line - its
pointless having an archive as the first file argument because none of
the contained objects will ever be pulled in.
Sam - any ideas how to solve this?
