We may want to runtime-optimize some core functions (str*, mem*),
but not have this leak into libstub and cause build issues.
Instead libstub, for the short while it's running, should just use
the generic implementation.

So, to be able to determine whether functions, that are used both in
libstub and the main kernel, are getting compiled as part of libstub or
not, add a compile-flag we can check via #ifdef.
