From: Paolo 'Blaisorblade' Giarrusso <[email protected]>
GCC hardened introduces additional symbol refererences (for the canary and
friends), also in modules - add weak export_symbols for them. We already tested
that the weak declaration creates no problem on both GCC's providing the
function definition and on GCC's which don't provide it.
