As well as this you may also need to stop prelink from breaking the
cross-compiled binaries.  This can be particularly insidious because
the binary will work after installation right up til the next
overnight prelink run.

Here's how to stop prelink:

%install
...
mkdir -p $RPM_BUILD_ROOT/etc/prelink.conf.d
echo '-b /usr/bin/name' > $RPM_BUILD_ROOT/etc/prelink.conf.d/%{name}.conf
