Hi Doug,
I tried what you said:

rpmbuild --ba --target=ppc  --define "CFLAGS \$RPM_OPT_FLAGS" libibverbs.spec

But still got '--libdir=/usr/lib64' in the options to the configure during rpmbuild.

In the libibverbs.spec:
%build
%configure
make %{?_smp_mflags}

Both rpm-devel.ppc and rpm-devel.ppc64 are installed.
What is wrong?
