Well kernel modules don't explicitly link to libgcc, they can only use
symbols exported by the kernel. In my case the kernel exports __sdivsi3
but the module compile generated  __sdivsi3_i4 which obviously fails to
link.

Also adding to the confusion is why the compiler feels the need to do a
division for a *particular* function call where other calls to the
*same* function do not cause this code to be generated.

A bit thanks. Now at least I know what it is, but not why its trying to
do it.
