This has always been confusing, and the idea of these functions returning the
number of interfaces initialized was half-baked and ultimately pointless.
Instead, act more like regular functions and return < 0 on failure, >= 0 on
success.
This change shouldn't break anything.

i'm not sure these changes are useful. the resolution of the symbols happens
at link time, so it isnt like gcc will be able to optimize away the default.
if anything, it'd make more sense to declare the functions as external/weak,
and then check that the pointer is not NULL. that'd save on the overhead of
having uncalled stub functions that merely return 0 in the final linked image.

This did work as I hoped on my PPC eval board, but maybe not globally.
I remember that initially, with the functions defined as weak but with
no body, check for NULL didn't work. I've never tried declaring them as
external, though.
thanks,
Ben
