this is not a standard setup, Eric Botcazou suggested to bring up the issue
here. For 3.3.x, 3.4.x and some versions before, Debian uses a biarch setup,
defaulting the compiler to 32bit, and having additional support for 64bit. With
current mainline this setup currently bootstraps, but fails to build the 64bit
libstdc++. A similiar failure in libstdc++ is seen, when configuring a biarch
compiler for ix86/x86_64, defaulting to ix86 (will open a separate report).
