OK, it looks like this problem might have been resolved in more recent versions
of binutils.
From 
https://fossies.org/dox/binutils-2.26/elf_8c_source.html
I see that the code is now:

 2289   if (sections_being_created && sections_being_created_abfd == abfd)
 2290     sections_being_created [shindex] = FALSE;

while it used to read just:

  if (sections_being_created)
    sections_being_created [shindex] = FALSE;

... and this change would have fixed the bug.  
I think it would make sense, though, to backport the bug-fix to older versions
of binutils-- if that's something that you do.
