I hoped we could, but when binutils removes the section the symbol
will be put into a random other section. I don't know how we could
really detect that has happened. Too bad the fix for this bug was
reverted. It really should be fixed properly in binutils ld, so that
it tracks which sections have symbols, and if so keeps the section
around even when it looks empty. binutild gold doesn't have this issue.
For Fedora I am using this very lame "workaround" for now:
http://pkgs.fedoraproject.org/cgit/elfutils.git/commit/?id=1d2f5631a4d211409c367669e7b838ec7210212c
Thinking about it again, maybe we should make some kind of --gnu-ld
exception for zero sized symbols? But I am afraid that catched too
much.
Cheers,
Mark
