The partial linking patch changes how objects are specified to the linker and breaks boards with an embedded environment. So we need to tweak the list of objects we specify via the linker script that go in the gap before the embedded env to work with this new behavior. This fixes linker errors for all the boards in question. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
