It's still a bit fragile since you do something that kbuild doesn't
expect with having a file in both a module and built-in code
in some configurations. I'm fairly sure this version works today,
but it would break the next time that file gets changed to include
a reference to THIS_MODULE, or anything else that is different
between built-in and modular code.

Another alternative would be to mark all symbols in this file
'static' and then include skx_common.c from the other two files.
Of course that is also ugly and it increases the overall code size,
so I don't see a way to win this.
