[PATCH] Fix stripping of objects where empty sections preceede .dynamic

Approved, but ...

Personally I would suggest that the second test should be:

          || SECTION_SIZE (section, segment) > 0

Just to make it clear that this is a test for non-empty sections.

Also I prefer strcmp()'s that explicitly test their result, rather than 
converting a trinary value into a boolean one.  ie:

    || strcmp (bfd_get_section_name (ibfd, section), ".dynamic") != 0)

In fact I much prefer using an alias called "streq" which makes the code 
easier to read, but that would involve changing lots of source files... :-)
