f21df05 was never supposed to be merged into the master branch.
fluffypony merged #3670 before #3668 was rebased and resolved.
Note: the cherry-picked commit hashes are now invalid because #3670
was merged before #3668 was rebased with the updated repo location.
Though we only need miniupnpc, rebasing and maintaining a miniupnpc-only
repo is unrealistic.
(cherry picked from commit 3c40eb768c292a4dec79d7dffd6685fd37940a2a)
