When gcc uses --build-id by default, the gate.lds.S linker script runs afoul
of the new note section and produces a bad DSO image. This fixes it.

I wonder why we bother having --build-id.

Any news on this? It does not appear to have been commited to git.
This issue is blocking our bringup of Fedora on ia64. The Fedora gcc
uses the --build-id option by default leading to a hang during bootup
without this patch.
