Do not give spurious errors about segment alignment.

This would happen if a later object segment had a more restrictive alignment than previous object segments that contribute to the same load segment, as in the following example:

s1      start
        jsl s2
        rtl
        end

        align   256
s2      start
        rtl
        end

These alignment requirements can be satisfied by just giving the load segment the most restrictive alignment of any object segment (since all alignments are powers of 2) and inserting space as necessary to align the code from each object segment.
