LU-2784 build: Provide RPMs build for Xeon Phi(TM) card

Enhance Lustre build to provide RPMs which can be installed on
Xeon Phi(TM) card automatically. This means the binaries
should be compiled by cross compiler and deployed into Xeon
Phi(TM) infrastructure on host to be automatically installed
on card after boot.

To produce Lustre client RPMs for Xeon Phi(TM) card just
execute the following commands:

export PATH=/usr/linux-k1om-4.7/bin:$PATH

sh ./autogen.sh

./configure --with-linux=/opt/intel/mic/src/card/kernel \
    --disable-server --without-o2ib \
    --host=x86_64-k1om-linux --build=x86_64-pc-linux

make rpms

NOTE: You should have "intel-mic-gpl-<version>.x86_64" package
installed and MIC GPL sources unpacked in /opt/intel/mic/src.

and the following RPMs will be produced:

lustre-client-mic-<version>.x86_64.rpm
lustre-client-mic-debuginfo-<version>.x86_64.rpm
lustre-client-mic-modules-<version>.x86_64.rpm
lustre-client-mic-source-<version>.x86_64.rpm
lustre-client-mic-tests-<version>.x86_64.rpm
lustre-client-mic-<version>.src.rpm
