I no longer get this issue since I have switched my build/host machine from
Ubuntu 11.10 to 12.04 (with same CT-NG version and .config).

I saw on IRC that Yann had a working fix for this. Yann, can you give us more
information?

Linaro's CT-NG 1.13.1 fork has a patch for the link with GCC 4.7. I don't know
if it's related to this issue:
https://launchpad.net/linaro-toolchain-binaries/trunk/2012.04/+download/crosstool-ng-linaro-1.13.1-2012.04-20120426.tar.bz2
/crosstool-ng-linaro-1.13.1-2012.04-20120426/contrib/linaro/patches/gcc/linaro-4.7-2012.04/link-with-cxx.patch

BenoÃt
