iceweasel built against 1.4.13-stable-1 which was built a long time ago,
like libstartup-notification had, and 1.4.14b-stable-1 currently in
unstable doesn't export the symbols. Same conclusion as with
libstartup-notification: old toolchain bug.

Still, I think it's wrong that a random library can highjack symbols
that gcc uses to call its own stuff from libgcc. Are there actual
legitimate uses of that "feature"?
