 My working assumption is that gdb is confused about i386 vs x86_64
 because it is unable to parse the XML target description, which in
 turn is due to the XML support being disabled in the NetBSD build.
 That would count as "NetSBD specific" in my book.

 No, it does not:
 
   # gdb /netbsd
   GNU gdb (GDB) 8.0.1
   [...]
   Reading symbols from /netbsd...done.
   (gdb) set architecture i386:x86-64:intel
