This will be magically fixed when koji switches to i586.rpm or i686.rpm
packages.  g++ by default uses -march=i586 unless -march is specified,
so the above only fails if you explicitly build with -march=i386.

The reason for switch to i586.rpm (or i686.rpm) is primarily the __sync_*
builtins, OpenMP #pragma omp atomic and the fact that for some years
glibc*.i386.rpm doesn't support pre-i486 anyway, neither does libstdc++ nor
libgomp, nor any statically linked programs.
