page-size-indicator

    An integer that specifies a page size as the power of 2 required
    to create a page that size. For example, to get an 8 KB page
    size, specify the value 13 because 2[13] equals 8K. The following
    table lists the page sizes supported by the linker with the
    defaults:

            Page

            bytes     qualifier is not specified.

                      qualifier is specified without a value.
