RHEL 7 64-bit, install 32-bit libraries for legacy software?

We still have a need for 32bit libraries for legacy cross-compiles, can RHEL7 64-bit be installed with the 32-bit libraries same as we did in RHEL6? This works currently now with RHEL 6.5 by installing the 32-bit packages(RedHat RPMs) and all works well. Does anyone know?

Background, if we install RHEL 6.5 64-bit today as Desktop with no options, then install a series of 32-bit packages from RedHat on top(RPMS) our environment works really well. We cross compile to 32-bit binaries to run on another host platform. We'll need to replicate this if we go to RHEL 7. Any help is appreciated.

Thanks,
Ted
