[Buildroot] [PATCH 3/5] package/binutils: drop ARC-specific version

[Thomas Petazzoni via buildroot <buildroot@buildroot.org>]

A warning was sent to Synopsys ARC people in December 2025 that the
ARC support in Buildroot was poorly maintained and in particular the
ARC-pspecific toolchain components. Despite a reply that some effort
would be made [1], no contributions were actually done. Also, Alexey
Brodkin is no longer at Synopsys. Time to remove Synopsys ARC specific
toolchain and toolchain components.

This commit removes the ARC-specific binutils version.
