    Specifies the minimum number of contiguous, uninitialized pages
    that the linker must find in an image section before it can
    extract the pages from the image section and place them in a
    newly created demand-zero image section. By creating demand-zero
    image sections (image sections that do not contain initialized
    data), the linker can reduce the size of images.
