It turned out with vanilla upstream GCC 7.2 stuff could be built for ARC, what's more we may even build Linux kernel with rootfs and get it all running perfectly fine so why not use that? Essentially GCC from SNPS GitHub still has a lot of fixes and improvements most of which will be a part of the next upstream release but let's see how it goes and if we see vanilla GCC doesn't require way too many back-ported patches we'll be able to get rid of SNPS GitHub here at all. As of today the only really required back-port is the one for non-uClibc libc.
