I had the same issue with gcc-4.8 and I tried to fix it with the following patches (which was rejected): http://patchwork.ozlabs.org/patch/460494/ http://patchwork.ozlabs.org/patch/449686/ However, after some investigation, here is the right fix from upstream: http://patchwork.ozlabs.org/patch/470531/ The --disable-install-libiberty option was broken, that's why the internal libiberty.a was installed in HOST_DIR. Hopefully, the same patch apply on gcc-4.7: http://patchwork.ozlabs.org/patch/500445/ Care to test it ?

With old gcc version (like with 4.7.4), libiberty.a is copied to library directory and it's not the behavior we want. According to Arnout Vandecappelle, newer version of gcc have fixed the problem. But if you choose gcc 4.7.X, the problem is there. Therefore, I send this little patch which remove the bad file after the build is finished.
