Please find a tarball with prebuilt toolchain for ARC HS38 by that link:
https://www.dropbox.com/s/uvqla26pmq03h5u/br-2016.08-rc2-65-g11109fd-archs38.tar.gz?dl=0

Just FYI I built it from today's BR sources, i.e. this is gcc6 based with all latest fixes
for ARC on top of vanilla gcc 6.1.1.

That's a defconfig I used in Buildroot:
-------------------->8---------------------
BR2_arcle=y
BR2_archs38=y
BR2_TOOLCHAIN_BUILDROOT_INET_RPC=y
BR2_TOOLCHAIN_BUILDROOT_LOCALE=y
BR2_PACKAGE_ELFUTILS=y
-------------------->8---------------------
