Makefile: reset LD and AR environment variables
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.
