As doc/README.ARC says, pre-build ARC toolchains are available at the Synopsys GitHub page.
The bin files are prefixed with arc(eb)-buildroot-linux- for earlier releases, but with arc(eb)-snps-linux- for the latest releases (arc_gnu_2014.12_prebuilt_*).
For all the releases, the symbolic link, arc(eb)-linux-* is also prepared for each bin file, so it can be used as the default CROSS_COMPILE regardless of the toolchains version.

I would propose to use even simpler and more universal prefix which could be used with both ARC pre-built toolchains, your own toolchain built by Buildroot or even pre-built Buildroot toolchain (http://autobuild.buildroot.org/toolchains/tarballs/br-arcle-hs38-full-2015.0...): [1] "arc-linux-" for little-endian [2] "arceb-linux-"
Care to re-send your patch or I may do that change myself?
