I have the same problem on armeb-softfloat-linux-uclibc. I also have
apps that fail with __fixdfsi. Many of the busybox applets fail with
__udivsi3 (e.g. awk, ping, top, df, netstat, fdisk) - basically
anything that does a certain kind of floating point divide. They only
fail when that specific instruction is reached, so for example ash
would only fail if mod or div is used e.g. "echo $((5 % 2))" or "echo
$((16 / 4))".

So far I have been unable to construct a test case - my own test app
that does floating point div also works.

I suspect that it is a bug in gcc and the way it generates code on ARM
softfloat targets, but I have no idea how to find out.
