Sorry, I've somehow missed your email when going through the

Hmm, I'm not sure what the right solution is.  Commenting out the
offendig lines is OK as a workaround, but it breaks backward

Since this is a linker bug, I'm reluctant to add more hacks to fuse to
work around it.

You might like to report a bug for the binutils package.
