MinGW-32.

BUG: Fix BinaryImageToLabelMapFilter on 1D image.

The BinaryImageToLabelMapFilter partitions the input image into threads by
lines in the first dimension.  We cannot split along a scanline access.

Use an ImageRegionSplitterDirection with its Direction set to 0 to prevent
partitioning the threads on scannlines when there is only a single line.
