[Buildroot] [git commit branch/2025.02.x] package/gcc: drop ARC-specific version

commit: https://gitlab.com/buildroot.org/buildroot/-/commit/41cb2a744d080801d8f55b0b7e9a7179a6404a9a
branch: https://gitlab.com/buildroot.org/buildroot/-/tree/2025.02.x

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 gcc version.
