But CentOS 6 surely has those development libraries!  Probably they 
aren't installed
as default but then many other packages aren't either.  Usually when one 
needs something,
in this case the capability to produce apps for the 32-bit Linux/x86, 
then one installs it!
I would assume searching for 'glibc-devel' in the package manager would 
show what is
missing.  Another way is to spy via the package names. In this case 
finding for instance :

ftp://ftp.funet.fi/pub/linux/mirrors/centos/6.5/os/x86_64/Packages/glibc-devel-2.12-1.132.el6.i686.rpm

wasn't any rocket science at all...

If one hasn't any need to produce also 32-bit apps then making a 
"stripped" toolchain
which doesn't have any 32-bit support, via the --disable-multilib', is 
the way to go. Then
the 32-bit libgcc, libstdc++ etc will not be produced during the GCC build.
