The trouble as I understand it is we need to know both the dependency name and the config/site cache name. We'll probably have to change siteconfig.bbclass to generate libc_config instead of ${PN}_config (create an intermediate variable the libc recipes override). We can then specify something like virtual/libc:libc in TOOLCHAIN_NEED_CONFIGSITE_CACHE. Of course that probably still won't work if you actually try and build meta-toolchain, we might just have to skip things that don't exist...
