[uClibc]new `dummy' main reference

[Miles Bader]

I see in crt0.s the new code:

   /* Stick in a dummy reference to main(), so that if an application
    * is linking when the main() function is in a static library (.a)
    * we can be sure that main() actually gets linked in */
   L_dummy_main_reference:
           .long	main

Can you explain in more detail when this is required?

Since crt0 calls __uClibc_main, and __uClibc_main calls main, isn't
main always pulled in anyway?

Thanks,

-Miles
