Linking libraries with Weak symbols

Done that. Even tried hacking with by using PlatformIO’s advanced scripting but none of that should be necessary since PlatformIO has a builtin mechanism for this problem (the lib_archive = false option) but I can’t seem to get it to work. I escalated it up to a GitHub issue `lib_archive = false` not disabling library archiving · Issue #205 · platformio/platform-ststm32 · GitHub

Thanks for looking.
