t/perf/run: copy config.mak.autogen & friends to build area

navytux · gitster · commit cd5c2812b6a8 · 2016-09-15T13:41:11.000-07:00
Otherwise for people who use autotools-based configure in main worktree, the performance testing results will be inconsistent as work and build trees could be using e.g. different optimization levels. See e.g. http://public-inbox.org/git/20160818175222.bmm3ivjheokf2qzl@sigill.intra.peff.net/ for example. NOTE config.status has to be copied because otherwise without it the build would want to run reconfigure this way loosing just copied config.mak.autogen.
