Thanks for the clear analysis and patch.  I think I prefer not to copy
the hack I added in elf_fake_sections when it ought to work to simply
do the following:

	* objcopy.c (setup_section): Act on make_nobits after calling
	bfd_copy_private_section_data.

Do you have a testcase we could add to the binutils testsuite?
