These functions are used by gcc to implement operations not present in
the host CPU (in this case, unsigned integer division). Normally these
functions are in libgcc, so if your build isn't finding them then it's
probably because either the gcc installation is broken, or the linker
is not finding libgcc. You can try adding -lgcc to your LDFLAGS (and
maybe the corresponding -L flag to tell the linker where to find it)
however as far as I know this should not be necessary.

Oh, the other thing that can cause this kind of thing is to specify
the linker directly (eg LD=your-arch-ld) when invoking configure as
the linker doesn't know about those gcc magic functions. The fix is to
tell configure to use gcc as the linker (which should be the default).

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
