Subject: [PATCH] make LOAD segment extensions based on p_align instead of
 pagesize

Since the p_align of the LOAD segment is no longer pagesize, the actual p_align
value is used to calculate for the LOAD segment extension.

If calculated with pagesize, new LOAD segment may be added even though the
existing LOAD segment can be extended.
