Hi Naresh,

I added this to the SVN repo's SConstruct this morning, and tested it
a cross building for a powerpc 85xx using ELDK 4.2.  There was a small
problem in VRRP related to pointer alignment, that I think you'll find
with the arm as well, but other than that it built fine.

For reference, the command line I used was:

    scons CC=powerpc-linux-gcc CXX=powerpc-linux-g++ STRIP=powerpc-linux-strip arch=powerpc os=linux strip=True DESTDIR=/tmp/foo install

Hope this helps.
