build-many-glibcs.py works for ARC now - after the 2 backports to gcc 7.2

ATM we have around 200 failures for upstream tools (likely due to libgcc unwinder 
patch not yet merged upstream). And just for data point, with github based gcc 
including the non-merged patches that number comes down to ~100. Bunch of them are 
in math/doubler and some in backtrace/nptl. Will this be considered a blocker. I'm 
almost ready for next round, rebased recently !
