[PATCH] buildman: Switch ARC toolchain to the upstream version

Good catch. I did run test on most of ARC boards except this one
as I forgot that it really differs from the original "hsdk" :)

So, that failure happens because of missing patch on GCC12, which
adds that new "mcpu", see [1]. It's now a part of GCC 13 and so I would suggest
the following "fix":

I.e. bumping default toolchains to GCC 13.x.
Do you think it's doable at this point?
