It's possible, but some more is still needed to have them built by the
normal buildds. Wanna-build needs support for cross-arch dependencies;
that's not been done yet. Splitting (multiarching) libc++-dev is also
needed to build the g++ cross-compiler, http://bugs.debian.org/678623
and it would need either a small source package to the do the
non-standard GCC_TARGET=foo dpkg-buildpackage build, or a bit more
work to make it standard. 

Thibg's final report gives a useful summary: 
and this blog post gives some more details:
