Thanks for looking into this again!

Your patch works fine with no regressions on s390-ibm-linux and
s390x-ibm-linux.  I'll be happy to do the watchpoint bits once

This means FETCH_INFERIOR_REGISTERS needs to be kept around in various
nm-linux.h files for now?   I'd have hoped to get rid of at least the
