De esta resposta no Stack Overflow:
You're missing the 32 bit libc dev package:
On Red Hat distros, the package name is
glibc-devel.i686
.
Provavelmente no Fedora é o mesmo nome do pacote. Isso também confirma isso:
[root at prophead ~]# rpm --qf %{NAME}-%{ARCH}\n -qf /usr/include/gnu/stubs-64.h
glibc-devel-x86_64
[root at prophead ~]# rpm --qf %{NAME}-%{ARCH}\n -qf /usr/include/gnu/stubs-32.h
glibc-devel-i686
