I'm not sure if this is going to fly, weak symbols work on the compilers I'm using, but whether they work for all of the affected architectures I can't say. I've cc'ed as many arch maintainers/lists as I could find. But assuming they do, we can use a weak empty definition of pcibios_add_platform_entries() to avoid having an empty definition on every arch.
