Toolchain built for ARCv1 (read for ARC700 cores) by default has disabled atomic ops (-mno-atomic). When we build Linux kernel for ARC770 which has LL/SC instructions and thus may handle normally atomic ops we explicitly add "-matomic" in CFLAGS. But since user-space perf utility has no way to extract CPU config options from Kconfig/defconfig it uses compiler default settings. In case of ARCv2 (read ARC HS38) atomics are enabled by default and so perf builds perfectly fine thus reenabling perf for ARC HS38 (actually for non-ARC700 targets).
