The above is not an error, just a context of some error.
I guess the error is that /usr/include/gnu/stubs-32.h doesn't exist
on your box, which is easily solvable by
sudo yum install /usr/include/gnu/stubs-32.h
(which is the same as
sudo yum install glibc-devel.i686
).  You want also 32-bit libgcc if you don't have it installed,
so
sudo yum install glibc-devel.i686 libgcc.i686
