arc: use more universal prefix for default CROSS_COMPILE

As doc/README.ARC says, pre-build ARC toolchains are available at the Synopsys GitHub page.

The bin files are prefixed with arc(eb)-buildroot-linux- for earlier releases, but with arc(eb)-snps-linux- for the latest releases.

The symbolic links prefixed with arc(eb)-linux- are also available for all the release, so those prefixes can be used as the default CROSS_COMPILE regardless of the toolchains version/variants.

---

Changes in v2:
- Use "arc(eb)-linux-" rather than "arc(eb)-linux-uclibc-"
