[ewg] Build issues with OFED-3.2-rc1 on ppc64

[Pavaman Subramaniyam]

Hi Vladimir,

I have installed OFED-3.2-rc1.tgz on SLES11 SP2 machine and tried 
./install.sh script with options 2 and 3.
The compat-rdma RPM build fails as follows:

Build compat-rdma RPM

Failed to build compat-rdma RPM
See /tmp/OFED.13846.logs/compat-rdma.rpmbuild.log

Upon seeing the log file, we come across that cxgb4/device.c is failing to 
compile.

Reported the same issue in opefabrics bugzilla 2360.
As a work around we need to ignore building and installing libcxgb4 and 
cxgb4 modules by selecting 4) Customize option of ./install.pl script and 
not selecting these modules.


Thanks and Regards,
