Indeed there're pre-built versions of tools for ARC.
Please look here:
https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/tag/arc-4.8-R2

There're separate tarballs for:
1. Elf32 and uClibc
2. For Debian/Ubuntu and RedHat/Fedora/CentOS
3. Little- and big-endian targets

You need only uClibc tools.

So for Debian/Ubuntu host you need following.
Little-endian toolchain:
https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/download/arc-4.8-R2/arc_gnu_4.8-R2_prebuilt_uclibc_le_ubuntu_install.tar.gz

Big-endian toolchain:
https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/download/arc-4.8-R2/arc_gnu_4.8-R2_prebuilt_uclibc_be_ubuntu_install.tar.gz


So for RedHat-based host you need following.
Little-endian toolchain: 
https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/download/arc-4.8-R2/arc_gnu_4.8-R2_prebuilt_uclibc_le_rhel6_install.tar.gz

Big-endian toolchain:
https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/download/arc-4.8-R2/arc_gnu_4.8-R2_prebuilt_uclibc_be_rhel6_install.tar.gz

Just extract corresponding tarball anywhere on your hos and add path to
"bin/" folder in your PATH env var.

Also you'll need to set ARCH env var to "arc".
