I got this far with no problems (thanks!), but my old branches don't
seem to have any common commits with the new binutils-gdb/master. Are
you doing the rebase with an explicit merge-base (e.g., "git branch
new-branch binutils-gdb/master;  git rebase --onto new-branch
old-master old-branch")? Or should "git rebase binutils-gdb/master
old-branch" work? (I'm hesitant to try that.)
