Allow specifying internal dependencies as either mandatory or optional.
Specifying a dependency as optional will mean that the component being
built will be skipped if said dependency is not being built. At build
time, the build system will resolve any optional dependencies and add
them to the list of dependencies to be built. Any source files requiring
said optional depepdencies will still have to be added explicitly to the
build by the respective component (e.g. adding BPF-related files when BPF
support is being built).

v4 -> v5:
- Automatically handle optional dependencies based on Bruce's
