Remove any reference to libfloat. That has gone once and for all.

Rationale:
Most of the time, soft-float problems are caused by this sucker of gcc:
it has support for soft float for all of the targets I've tried so far,
but does not activate this code until you dwelve into half a dozen of
files to make it accept to build and link the support code...

So, yes: gcc has soft-float support. And again, yes: gcc is a sucker.
     1 The following fixes an error that occurs when building glibc-2.3.2 (but not glibc-2.2.5) for sh4:

    32 It seems that the definitions in asm/user.h and the above patch collide.
    33 I'm not sure why you need this patch, but is it needed for the problem
    34 about struct ustat that you pointed out in this list, isn't it?
    35 I found why I don't hit ustat problem - my local kernel tree includes
    36 the following patch, though I can't recall about it.
    37 
    38 Regards,
