configure: don't generate warnings on missing features
New users get confused by the warnings generated by configure about non-essential features.
Language should be updated to be informational, or perhaps not mention it at all beyond configures normal output. The summary at the end could be enough.

Not really. The table/listing at the end of configure we have now might be good enough for most cases, but it'd be nice to also output the package names for installing the dependency of a feature somewhere. Currently that is part of the warning/error messages.
