It is not a problem, just build in another directory and your OE build
trees will be completely independent. You should be even share the same
tree environment with different config files. The only situation when OE
will fail would be (host_triplet == build_triplet), because staging and
build root will go into the same directory. It needs fix in OE.

Do you really need it? The whole openSUSE project is a bi-arch, but it
can live without cross-build trees. Baselibs utility operates on final
binary packages. Only compiler for build system compiler you may want to
provide 32-bit target support.

If you are trying to build x86_64 compiler for i586 target on an
arbitrary host, then you may recycle generic support for canadian
toolchain, that was added few months ago (well I did not tried it yet).
