[ewg] Build issues with OFED-3.5 on ppc64

[Pavaman Subramaniyam]

Hi Vladimir,

I have installed OFED-3.5-20120716-0723.tgz on RHEL 6.2 machine and tried 
./install.sh script with options 2 and 3.
The compat-rdma RPM build fails as follows:

=====================================================================================

There is /usr/src/kernels/2.6.32-220.el6.ppc64/arch/powerpc directory and 
not  /usr/src/kernels/2.6.32-220.el6.ppc64/arch/ppc64 as being looked for 
building compat-rdma.
Similar issue was reported for building OFED-3.2 on SLES11SP2 GMC for 
ppc64.


Thanks and Regards,
