He wrote

which tells http://kegel.com/crosstool/crosstool-0.28-rc37/crosstool.sh.txt
to configure gcc with --with-float=soft
and glibc with --without-fp.

I rather thought that would do it, but I guess it
doesn't pass your test, i.e. a compiler configured for
soft-float should output
  #define _SOFT_FLOAT 1
when you run the command
  $TARGET-gcc -dM -E -xc /dev/null  | grep FLOAT
Can somebody who knows something about softfloat comment?

Incidentally, I seem to recall softfloat is said to not be fully working
with vanilla gcc-3.3.3, the version Steven is trying.  Steven,
can you try with gcc-3.4.3 just for kicks?
