[PATCH v3] strip: keep .ctf section in stripped file

I think that the function that does this is "is_strip_section_1" in
binutils/objcopy.c.  If an input section has the BSF_DEBUGGING flag
set (an internal flag to he BFD library, but basically it should be
set for all debug sections, including .ctf sections I think), then
the basic decision is to keep the section unless -g is used.
