No, you need to get the original build logs.

The binary should contain the full build version (ie the QEMU version
and the distro specific package release).

On Fedora we build with the "annobin" plugin, which records some info
about GCC options in the binary, but that's still quite distinct from
any configure args.

For Fedora the logs are all publically available at a predictable URL e.g.




Not sure where other distros might store this info. If people have info
for more distros, perhaps we could create a wiki page making a list of
where each distro keeps its biuld logs ?
