 I just tried that, but it seems to make things worse, not better:
 
   ./build.sh -j 4 -V MKDEBUG=YES -V COPTS="-g -fdebug-prefix-map=$(pwd)=/usr/src" -V CONFIGOPTS="-D DEBUG=-g" -O /tmp/obj.amd64 -m amd64 -U release sourcesets
   [...]
   # gdb /netbsd
   [...]
   Reading symbols from /netbsd...(no debugging symbols found)...done.
   [...]
   (gdb) l sys_sync
   No symbol table is loaded.  Use the "file" command.
   (gdb)
