perf_counter tools: Cleanup Makefile
perf_counter tools: Cleanup Makefile

We currently build perf-stat/record etc, only to do nothing
with them.  We also install the perf binary in two places,
$prefix/bin and $perfexec_instdir, which appears to be for
binaries which perf would exec were a command not linked in.
Correct this, and comment out broken/incomplete targets dist
and coverage.
