the current gcc-4.6/eglibc is now built multilib'd for -mfloat-abi=softfp|hard, including the GCC runtime libraries. I hope that the gcc cross builds will pick this up soonish, not needing to build the cross compiler twice for softfp and hard float-abi.

How does that actually work to select the runtime linker? I was looking into setting the --dynamic-linker from -mfloat-abi=* flags, but didn't manage to. Apparently, this is getting resolved for gcc 4.7, but I was curious how you dealt with this for gcc-4.6.

It's not handled. So the only way is currently to use a LD_LIBRARY_PATH and non-conflicting command line options (which at least works for the currently built runtime libraries).

Can you take a looks at bug 816852 [1] where I collected some patches which allow to build non-multilib cross compiler? Yesterday I uploaded packages built in old style (no multilib).
So far I was not able to build multilib cross compiler for armel (with armel and armhf cross libc6-dev installed).
