[PATCH] uml: export symbols added by GCC hardened

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.
