No, it is a user error.  The packaging goal is that nobody is forced to have
32-bit packages installed on x86_64 (and similarly for other architectures).
So, if you want to compile/link 32-bit packages, you need to install a
minimal set of 32-bit packages (at least
yum install glibc-devel.i686 libgcc.i686
).
