None of our customers asked for it yet, and nobody  else  contributed
it either.

I'm not surprised.

I guess you mis-configured the tools so you now  run  into  endianess
problems?

In general,  cross  compiling  is  as  trivial  as  adding  a  "CC  =
$(CROSS_COMPILE)gcc"  line  to  the Makefile. At least for any source
that was  portably  written  and  does  not  need  any  autoconfig  /
configure stuff to be built.

Did you turn on debugging?

Did you turn on debugging?

It should work.
