Comment # 2 on bug 1218701 from Fabian Vogt

Looking at the build log, there is this diff:

-  -- LLVM host triple: i586-suse-linux
-  -- LLVM default target triple: i586-suse-linux
+  -- LLVM host triple: i686-suse-linux
+  -- LLVM default target triple: i686-suse-linux

Which is coming from %_host_cpu:

# Figure out the host triple.
%ifarch armv6hl
# See https://build.opensuse.org/request/show/968066.
%define host_cpu armv6kz
%else
%define host_cpu %{_host_cpu}
%endif

The build happens on a recent x86_64 VM with an x86_64 kernel and 32bit x86
userspace, so technically i686 is actually more correct than i586 and IMO not
an RPM regression.

I guess the clang-tidy testsuite failure is because of
https://github.com/llvm/llvm-project/issues/40805, which is related to floating
point precision.
