Nuke maemo (nokian800/nokian900) and [open]pandora targets

They haven't seen any work since 2013, and likely hasn't compiled in at
least a couple of releases -- not that we ever "released" anything for
these targets.

Futhermore, upstream for both has been effectively dead for about as
long, and there's been no user reports of these being used since 2017
(and even then only in passing).

It isn't worth the effort to triage their current state, much less
uplift into something supportable, while the maintenance burden of
keeping these things in-tree can be demonstrated by the diffstat.
