how to have mock use arch i686?

[Matt Domsch]

This post suggests I need to be building packages using arch i686
instead of i386 as mock does by default.  If so, how do I go about
doing so?

Thanks,
Matt

The -march=i386 is added by /usr/lib/rpm/redhat/rpmrc

The FTBFS system uses i386 build architecture. Koji uses i686 architecture
which has no problem with the compilation.

I fixed it by overriding CXXFLAXS on i386:
%ifarch i386
export CXXFLAGS="%{__global_cflags} -m32 -fasynchronous-unwind-tables"
%endif
