Joel, Although possibly not fully optimized, soft float configuration for armv4t should still run on armv7. To build your own, I think you'll have to patch the gcc source code to enable multilib (disabled by default) and build the C library twice and figure out a way to combine them. Not exactly sure of the exact process since it's not something we currently do or support.
Thanks!
