* - null identifies that this section does not need to be added to the
* output image (ie. shared object sections or sections we're going to
* recreate (sym tables, string tables, relocations, etc.)).
*
* - any user defined section will be first in the associated segment.
*
* - interp and capabilities sections are next, as these are accessed
* immediately the first page of the image is mapped.
*
* - objects that do not provide an interp normally have a read-only
* .dynamic section that comes next (in this case, there is no need to
* update a DT_DEBUG entry at runtime).
*
* - the syminfo, hash, dynsym, dynstr and rel's are grouped together as
* these will all be accessed together by ld.so.1 to perform relocations.
*
* - the got, dynamic, and plt are grouped together as these may also be
* accessed first by ld.so.1 to perform relocations, fill in DT_DEBUG
* (executables only), and .plt[0].
*
* - unknown sections (stabs, comments, etc.) go at the end.
*
* Note that .tlsbss/.bss are given the largest identifiers. This insures that
* if any unknown sections become associated to the same segment as the .bss,
* the .bss sections are always the last section in the segment.
