Just for a while, we should get this fixed for v5.17, for v5.16 a revert
is required :-\

Right, its nice that I have a mechanism to test build in 80+ distro
versions/cross-build environments. :-)

And I'll add this to 'make -C tools/perf build-test' too, what I have in
rx_and_build.sh is a limited set of 'build-test', building with it in
all containers take more time, it is possible if one does:
[perfbuilder@...e ~]$ export BUILD_TARBALL=http://192.168.100.2/perf/perf-5.16.0-rc8.tar.xz
[perfbuilder@...e ~]$ export BUILD_CMD='make -C tools/perf build-cmd'
[perfbuilder@...e ~]$ dm
Then it will do it for gcc and for clang, takes a while...
My Dockerfile for tumbleweed, btw, is:

Yeah, but I did it already for quite a few distros :-)
