Skip filesize check when matching segments.

Here is a proposed patch.  It does two things:

  1,. It adds a warning when a NULL GNU_RELO segment is going to be generated.

  2. It skips the p_filesz check when matching real segments to the requested
GNU_RELRO segment.

I suspect that 2) will rejected and the correct patch will be to fix the
generation of the initial segment map.  But at least now the problem is out
there for people to look at.
