GCC9 on 32bit systems might warn about '%s' directive argument is null
for symname in backtrace-dwarf.c. Just check whether symname is NULL.

During fuzzing of the new xlate_notes testcase I noticed that

infinite loop going over all ELF notes. Fix by adding an overflow
check before updating offset.

In the case I brought up you're saying it was an elfutils' libdw decision to
provide negative number as DW_OP_plus_uconst (unsigned constant)? So there
would be no harm to cast it to a signed int??
Do you know if the
