Standard linux distros out there like debian or gentoo already ship a biarch gcc per default. It wouldn't seem odd to me if OE had an option to enable the generation of a biarch compiler. > I think my biggest worry is the "--enable-targets=all" option which may > or may not enable things we might not want enabled.

I did not find any other way of enabling both -m32 and -m64 switches in gcc. I've been successfully using this patch to generate a complete x86 32bit distro with a 64bit Xen hypervisor (I believe the result would have been the same if I tried to compile a 64bit linux kernel). I did not have any issues with it so far.
