This is my qemu binary compiled with --prefix=/nonexistent
bash-5.1# ./qemu-system-x86_64 -L help

bash-5.1# ./qemu-system-x86_64 --help|grep helper
[,br=bridge][,helper=helper][,sndbuf=nbytes][,vnet_hdr=on|off][,vhost=on|off]
use network helper 'helper'
(default=/nonexistent/libexec/qemu-bridge-helper) to
-netdev bridge,id=str[,br=bridge][,helper=helper]
using the program 'helper
(default=/nonexistent/libexec/qemu-bridge-helper)
See that it will call /nonexistent/libexec/qemu-bridge-helper by default.

Thanks Paola,
We are still in testing and that's the only thing we've uncovered so
far with the new 5.2.0. I will post if the ops guys find anything else.
Hmm, that's weird though. The path to the default bridge helper is
relocated:
net/tap.c: helper = default_helper =
get_relocated_path(DEFAULT_BRIDGE_HELPER);
