The goal is to fix the compilation of perf (from linux) when LD or AR variables are inherited from the environment. After the linux upstream commits 5ef7bbb09f7b ("perf tools: Allow to specify custom linker command") and 3c71ba3f80bb ("perf tools: Really allow to specify custom CC, AR or LD") CC, AR, and LD variables are not overridden if they are inherited. In case of a cross compilation, it results in an inconsistent state: CC is overridden but not LD and AR.
