The way gcc handles it is a single recipe responsible for the source
(gcc-source) which the other recipes all then depend upon.

The kernel works a bit differently as the kernel creates the shared
source and then the other recipes depend on virtual/kernel.

Both approaches have complications and end up needing to be special
cased in various places (archiver.bbclass for example) so they're
definitely advanced usage.
