Actually we've dealt with this already:

commit ce82ff05388b5ddafdf6082ef0776cce72c40b1c

    FPU POST: fix warnings when building with 2.18 binutils
    
    When compile u-boot with the 2.18 binutils the following
    warning messages for each object file in post/lib_ppc/fpu/ is
    produced at the linking stage:
    
    post/libpost.a(acc1.o) uses hard float, u-boot uses soft-float
    ...
    

...

However I think we just need to move the code a bit.  Will post a patch
