When it happens that the .gnu.version_r stores the strings in .dynstr it can
come to corruption of the library names written into DT_NEEDED:
-the library names in DT_NEEDED are replaced, new entries are written to the end
of .dynstr
-the version library names are replaced, and written to the end of the string
section.
If the section for the version strings is also ".dynstr", the previous
modifications were _not_ taken into account and things were written from the old
end of .dynstr again. The order in which these strings were written is not the
same as the previous replacement, so things would end up with the same size, but
different offsets. The .gnu.version_r table is correct, the file contents are
fine, but the offsets in the DT_NEEDED entries are wrong. Since they are printed
as 0-terminated strings the first one replaced will always be shown correct,
which also is the case if the argument is only used once as the string is
replaced with itself afterwards.
