…ux/kernel/git/acme/linux into perf/urgent

Pull perf/urgent fix from Arnaldo Carvalho de Melo:

  - Fix build breakage if prefix= is specified, this introduced
    a regression for a build idiom used by the Debian "linux-tools"
    package, that does:

       MAKE_PERF := $(MAKE) prefix=/usr V=1 ARCH=$(KERNEL_ARCH_PERF) ...

    Fix it. (Lukas Wunner)
