[RFC PATCH] bfd: Handle objcopy --only-keep-debug in _bfd_elf_init_private_section_data()

Hi Nick and Alan,

Thanks for the suggestion!  I tried both approaches but wasn't sure

I've tested v2 with the binutils testsuite.

Not yet, I just noticed that we have a
keep_debug_symbols_and_test_copy() test in objcopy.exp, I can take a
look later today if needed.

Thanks,
