Patchset:

PS2: I disagree strongly because I do not want a funky error prone chain of redirected symbols pointing to a now weak symbol, we are not writing libraries or frameworks, we are writing emebdded software, and the last thing I need are weak symbols with linker "oopsie woopesies" because due tue some other mishap the weak symbol was silently used and not overridden by something else and no one noticed anything. We want a handler, so either we have a handler, or a compile failure, and not schroedingers mystery firmware that compiles no matter what and that might or might not contain the function we are looking for. I can very well remember a funny parameter that allowed the simtrace firmware to build with missing symbols, that was really not fun to debug at the time because at runtime it called 0.
