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.
