From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>
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.
