Thanks for this suggestion, replacing ldm sp,{r0-r3} with ldmia sp,{r0-r3} does the trick!
Now, the kernel compiles fine, so the problem was the ldm instruction was not recognised from the cross-as.

You can also try replacing ldm with ldmia, but ldmia is supposed to be
the default for ldm where no suffix is specified, at least it is what
the documentation says.
