You won't need any ABI docs.  This is a good first step, but if you can
rebuild GNU make with debugging (-g) and without optimization (-O0) you
will hopefully get a much more interesting and useable core.  I'm
assuming, although I'm not familiar with working on ARM.

It looks like somewhere in the GNU make code we're passing an invalid
pointer to strlen(); either NULL or pointing to invalid memory of some
kind.
