I would guess this is because you are trying to set the libdir and
compile mode flags yourselves?  The rpmbuild environment has the ability
to set these things for you.  For example, if you build using this
command on a ppc64 machine:

rpmbuild --ba --target=ppc libibverbs.spec

and inside the libibverbs.spec file simply use %{_libdir} and CFLAGS=
$RPM_OPT_FLAGS, then you get the right result.

Likewise, rpmbuild --ba --target=ppc64 libibverbs.spec *also* does the
right thing if you use %{_libdir} during configure and in %files and
also set CFLAGS=$RPM_OPT_FLAGS.

The only requirement for this to work is that you need to have installed
rpm-devel.ppc and rpm-devel.ppc64 (you get the correct macros from those
different packages).

At least this is how it works under RHEL.  I would hope that SuSE is
sane in this regard too.

Trying to outsmart rpm instead of working with rpm on stuff like this is
a big part of why I want tarballs, not a distribution.  It breaks in all
sorts of subtle ways.

The ppc64 RPM_OPT_FLAGS include -m64 because we know that -m32 is the
default setting in the compiler and you need it to force 64bit apps.

Just perpetuating the real problem.

No, you need to file a bug with SuSE.  This is absolutely broken RPM
behavior.  Two packages by the same name but different arch are *not*
the same package and any recent version of rpm knows that.
