Issue Description:

Empty arrays are encoded into a JSON string in different ways on Darwin and Linux. This test will pass on Darwin:

  func testEmptyArray() throws {
    let encoder = JSONEncoder()
    encoder.outputFormatting = .prettyPrinted
    let value: [Int] = []

    XCTAssertEqual(String.init(decoding: try encoder.encode(value), as: UTF8.self) , """
[

]
""")
  }

but fails on Linux:

XCTAssertEqual failed: ("[
  
]") is not equal to ("[

]") -

I'm realizing that this also happens with empty objects.
