Hm. The discussion thread is about an application that is unnecessarily
linked to libgcc due to a presumed toolchain bug.

I don't claim that this is the case for busybox, 64bit arithmetic is
definately used there, so the linkage to libgcc is needed.

So it is more about getting rid of libgcc, even though it is needed. As
suggested, this can either be done by directly replacing the functions
(ie. __divdi3) or by providing substitutes (ie. div64()).
