Here are the results:
ligcc.a does not have any sf instructions.
busybox built as dynamic binary does not have any sf ins.
libc.so.6 has this:

I did:
mipsel-linux-objdump -S libc.so.6 | less
and then searching for $f (floating point registers)
If I link busybox static, I get those two functions linked in.
How to solve this?
One more thing.
I can compile strace only with gcc-3.3.4. With any other version
I get:
syscall.c:449: error: 'SYS_read' undeclared (first use in this function)
I applayed the patch for this, but it doesn't seem to help.
BR,
Matej
