In my quick scan over your patch, I didn't see anything that would set
ELFOSABI_GNU. Since SHF_GNU_RETAIN is in the SHF_MASKOS range,
generating sections with the flag set should also set OSABI, and
if an object has the wrong OSABI you can't interpret that bit as
SHF_GNU_RETAIN. See has_gnu_osabi for the way this is handled in
bfd.
