I think libdwfl functions that rely on the specifics of GNU/Linux
(kernel/modules, core file format, proc fs, signals/ptrace) can just
return NULL and fail on other platforms. So just ifdef out the code in
that file. And implement dwfl_linux_proc_attach and the internal
functions __libdwfl_ptrace_attach __libdwfl_ptrace_detach
dwfl_linux_proc_attach __libdwfl_get_pid_arg as always failing in that
case.
The attached patch seems to be working for me on kFreeBSD.
PS: run-nm-self.sh fails for me for current master.
