You cannot mix FPU-code and soft-float in one application/library setup.

If my kernel has fpu-emulation, do I need to compile soft-float into my glibc?
You can compile either ALL libraries and ALL applications with, or ALL without FP.

Does putting fpu-emulation in the kernel and not using soft-float in glibc
save me RAM?
Not any significant amount, I think.
Also be awre the the emulation code in the kernel is far from complete or perfect.

Does this mean you recommend no emulation code in the kernel and ALL libraries and ALL applications be compiled with -msoft-float?

For FPU-less systems: yes.
