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-2015.02.tar.bz2):
 [1] "arc-linux-" for little-endian
 [2] "arceb-linux-"

Care to re-send your patch or I may do that change myself?
