--- Comment #2 from Nick Clifton <nickc at redhat dot com> ---
The problem is cause by crt1.o containing multiple .gnu.build.note sections.
In the object file they are in the right order, but when linked with
gc-sections
enabled they end up in the wrong order.  Technically this is a violation of the
Watermark protocol, but in practice it no longer matters as the code has to
perform multiple passes over the notes anyway, so it can easily locate the
version notes during its first pass.  So I have updated objcopy's code to
remove the error message.
