Setting up an alternate build environment is the type of thing that I
like to do with bind mounts in a private namespace.  There's no standard
tool yet to create a private namespace, I simply use one that I hacked up;
with the merging of shared subtrees into 2.6.15, that ought to change.
The v9fs folks may have a set of userland tools available.

First,

   sed -e 's/x86_64/i686/;s/ppc64/ppc32/;s/s390x/s390/' \
	/etc/rpm/platform > /etc/rpm/platform32

In a private namespace, you can do something like:

   mount -n --bind /etc/rpm/plaform32 /etc/rpm/platform
   ...
