For a long time we used to hard-code CROSS_COMPILE prefix for ARC until it started to cause problems, so we decided to solely rely on CROSS_COMPILE externally set by a user: commit 40660f1f ("ARC: build: Don't set CROSS_COMPILE in arch's Makefile"). While it works perfectly fine for build-systems where the prefix gets defined anyways for us human beings it's quite an annoying requirement especially given most of time the same one prefix "arc-linux-" is all what we need. It looks like finally we're getting the best of both worlds: 1. W/o cross-toolchain we still may install headers, build .dtb etc 2. W/ cross-toolchain get the kerne built with only ARCH=arc Inspired by [1] & [2]. [1] http://lists.infradead.org/pipermail/linux-snps-arc/2019-May/005788.html [2] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=fc2b47b55f17 A side note: even though "cc-cross-prefix" does its job it pollutes console with output of "which" for all the prefixes it didn't manage to find a matching cross-compiler for like that: | # ARCH=arc make defconfig | which: no arceb-linux-gcc in (~/.local/bin:~/bin:/usr/bin:/usr/sbin) | *** Default configuration is based on 'nsim_hs_defconfig' Suggested-by:
