gcc 3.4 comes with softfloat support, but needs the patch that I quoted
to prevent it from giving an error about undefined symbols.  The end
product works fine.

gcc 4.0 also comes with softfloat support, but doesn't work without the
patch (gives an error about undefined symbols) nor with the patch (gives
an error about duplicate symbols.)
