We don't want to necessarily keep everything referenced by
relocs in .opd, as that would keep all functions. Instead,
if we reference an .opd symbol (a function descriptor), we
want to keep the function code symbol's section. This is
easy for global symbols, but for local syms we need to keep
information about the associated function section. Later, if
edit_opd deletes entries, we'll use this array to adjust
local syms in .opd. */
