A 64-bit kernel will run 32-bit binaries fine... Um, there may be a needed 
kernel option though... CONFIG_IA32_EMUL? Anyone?

Your CFLAGS in make.conf don't affect your kernel, normally.  I don't use 
genkernel maybe it does some crazy magic like that.

Just setting the proper processor type should build your kernel as 64-bit.
