Hm. It looks like this flags is already being in use on unstable these days.

At least I see it in all recent unstable builds, eg:

  https://buildd.debian.org/status/fetch.php?pkg=tevent&arch=amd64&ver=0.12.0-1&stamp=1651527651&raw=0

make[3]: Entering directory '/<<PKGBUILDDIR>>'
CC="x86_64-linux-gnu-gcc" CFLAGS="-g -O2 -ffile-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -Wformat ...

I don't really know where it is coming from (my guess is dpkg-buildflags),
but it looks like this issue has already been solved in a more general
way meanwhile.

Can we perhaps close this bugreport now?

Thanks,
