I have built it with crosstool 0.38

glibc

With -msoft-float everything is working fine, but with softfloat.
Without flags or with -mhard-float my toolchain (which is btw a
gcc-4.0.2, glibc 2.3.6) generates floating point instructions which I
can see in the objdump.
Since this seems more like a toolchain related problem, maybe the
crosstool ml is a better place for this.
