I believe the right fix is in glibc instead:
[patch] Fix vDSO l_name for GDB's: Can't read pathname for load map:Input/output error.
http://sourceware.org/ml/libc-alpha/2009-10/msg00001.html
Message-ID: <20091004161706.GA27450@host0.dyn.jankratochvil.net>

Could you verify it works for you so that we could possibly ping it?

Fedora is using a similar patch but that is IMO a wrong workaround:
http://pkgs.fedoraproject.org/cgit/gdb.git/tree/gdb-core-open-vdso-warning.patch

Thanks,
