You could do it for the toolchain, and use eselect to pick which one
should be active. For libc, I don't think it's possible.

No. If you want bash within the empty target directory, you also need
all it's dependencies in there.

I don't think that's how it works, but I'll be honest and say that I
haven't used this method myself. I've only done "direct" cross
compilation, without emerge.
