I order to build 32 bit programs on an x86_64 machine, I would create a
totally 32 bit chroot on that machine.
Inside the 32 bit chroot, you will still need to use "setarch i386" in
front of your make commands (or rpmbuild commands).
If you want to build 64bit stuff, you need to have a fully x86_64 only
machine (with the only x86 RPMS being glibc.i686 and glibc-devel.i386).
If you have other i386 rpms in the x86_64 build tree, you will
inevitably get 32bit stuff in your 64 bit compiles ... and if you have
x86_64 items in your i386 build tree, you will inevitably pollute your
32 bit items with 64bit libraries ...
