which was merged post RC2. I base this on the fact your build is failing
during the dynamic build. Do try a reverse patch and see if it helps.

Yes, that fixed the build with the standard bfd linker

(http://koji.fedoraproject.org/koji/taskinfo?taskID=6722847).

It seems to pass the dyn helloworld test at least.

I believe Karel is right - you just need to use Gold. Ben actually had
patches to make the build fail if using binutils ld was detected, but
I believe I had reservations about the patch which I cannot recall off
the top of my head. In any case, a fix like that can certainly go in
7.8.2.

If it doesn't then I think I can "bootstrap" to 7.8 with ld.bfd

and then rebuild with ld.gold so hopefully it should work out anyway.

Thanks, Jens
