[BUILDROBOT] gcc21 fails to build tilegx-linux

[Walter Lee]

Thanks for the bug report.  I have not been able to reproduce the link 
error in my environment, but I've committed a change to use g++ instead 
of gcc and I will see if the buildbot does better with that change.  The 
other issues I will fix when gcc is in stage 1.
