For completeness, on some arches like IA-64 there are some STB_LOCAL symbols
in .dynsym other than 0 and STT_SECTION, particularly those which are used
for relocations. But they don't appear in .hash and are looked at only when
resolving particular local relocation (ie. never visible outside
of the library).
