Version:        2
Release:        1%{?dist}
Summary:        Override RPM optflags for x86_64_v2 buildroots on EL10
License:        MIT
BuildArch:      noarch

%description
Overrides %%optflags to use -march=x86-64-v2 instead of the EL10 default
-march=x86-64-v3. Required in COPR alma-kitten+epel-10-x86_64_v2 chroot
where build hosts only support SSE4.2 and cannot execute v3 instructions.
