    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---------------------
