You need to double-check back to the oldest binutils version that we
support for building libc (>=2.20) that had STT_GNU_IFUNC support (from
NEWS looks like 2.20 itself did have it) to ensure that the script handles
the output from the readelf in all the intervening binutils releases.
If it's verified that the modified script works with all those versions of
readelf, then it looks fine.
