Oh, I see, thanks for your comment!. My intention with this patch is to
replicate the same proceeding by _default_ implemented in `binutils strip'
tool, it is: not remove CTF section, except it is indicated explicitly.

Of course, if you think it is not really a good idea, I can propose a
patch to change the invocation of `eu-strip' in `find-debuginfo.sh' to
preserve CTF section as you showed above, when it generates debug
packages.
