Probably revision 329997

The system has been plagued by stoppages during clang build.
Sometimes in llvm-tblgen, but not always. A frequent error
is 137, from clang, but "out of swap" happens too. Been using 
the -DNO_CLEAN option to pick up where it left off.

Ok, will try starting over. FWIW, recently behavior re swapping
has been much better (gstat delays look smaller using swap on 
microSD) but the system is still reporting "out of swap" when 
top shows less than complete swap use.

Thanks very much!
