Is the existing ./configure --with-pkgversion= option not enough?

Here is the system QEMU from Fedora 35:

  $ qemu-system-x86_64 --version
  QEMU emulator version 6.1.0 (qemu-6.1.0-10.fc35)
                                             ^^^^

Or on Debian:

  QEMU emulator version 5.2.0 (Debian 1:5.2+dfsg-11+deb11u1)
                               ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
