Merge bitcoin#34923: depends: remove workaround for Make older than 4.2.90

f1e14df depends: remove workaround for Make older than 4.2.90 (fanquake)

Pull request description:

  This was introduced for distros shipping older `make`, such as Ubuntu `20.04` (`4.2.1`). It's likely that any distros being used for Darwin and Windows cross compilation, are shipping a newer make at this point.
