package/gcc: enable ARC HS rel 3.10 in vanilla GCC 13+

For quite some time a special tuning for ARC HS release 3.10
was only implemented in ARC fork of GCC, thus there was a dependency
introduced back in the day, see [1].

But finally that tuning got merged upstream (see [2]) and
so could be used with vanilla GCC starting from version 13.1.
