Right, I'm seeing the same thing on mipsel now, so it looks like a
change introduced by new binutils.  I've attached xz_decompress.image.
"objdump -h" from a build on Debian wheezy looks like this:

"-R .MIPS.abiflags" seems to fix things; does that need to be added
anywhere other than gentpl.py:image?
