But, after reading all that, I realized I didn't actually answer your
question :)

That (/lib/x86_64-linux-gnu/libc.so.6) will do.  You're fine.  You don't
need a symlink or anything.
Your host gcc will know to look for libc.so.6 in the multiarch location
rather than in /lib.  That's all that really matters.
