--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
And it is an intentional disto decision, because 32-bit kernels aren't
supported (not even shipped) in RHEL and thus SSE2 is required.
You can always use -march=i386 or -mno-sse etc. to override the defaults.
E.g. in Fedora 32-bit CPUs are still supported and the configured compiler
defaults to -march=i686 for 32-bit compilation.
