Greetings,
currently we are maintaining own CentOS 7 i686 rebuild and I would like

kindly ask you to replace following macros from gcc.spec:
%if 0%{?rhel} >= 7 %ifarch %{ix86} --with-arch=x86-64 \ %endif %ifarch x86_64 --with-arch_32=x86-64 \ %endif
with that:
%if 0%{?rhel} >= 7 %ifarch %{ix86} --with-arch=i686 \ %endif %ifarch x86_64 --with-arch_32=i686 \ %endif
x86-64 causes gcc to use extended instruction set for produced code and it's impossible to run CentOS 7 i686 on older systems without SSE2 instruction because of SIGILL. This affects Pentium 3, old VIA CPUs, old Xeons and some others.
Is that possible?
Overall, I'm hesitant here as folks (some of the epel devs as well as others) are looking at this as a way to supplement the 32bit environment for the base distro for building things like wine. I don't want to mix gcc build options for things that may live in both places.
