Did you get anywhere with this? As Ludovic mentioned, it might make sense to work around it in gnu-build-system too if patching GCC turns out to be difficult. If we can't find a workaround in the coming weeks, perhaps we should postpone the issue and add package-specific workarounds in the mean time?
