It is weak because it it not a function call. It is just there
to ensure the linker does the Right Thing(tm). We want the
symbol there so we can be sure main() is linked in the app even
when it is hiding within an archive (.a), but we do not want to
supply the actual main() function, since apps work better when
using their own. :-)
