1) Build each benchmark regardless of the failure of any other benchmark to build.
2) Report the PASS or FAIL status of each benchmark during the build in a
     log/YYYYMMDD-HHMM/status.txt
   file where YYYYMMDD-HHMM is the time at which the build was run
3) Report the PASS state of a build (i.e. all benchmark built) by constructing a file
     log/YYYYMMDD-HHMM/pass.txt
   (for the same time as in point (1) ).
4) Report the FAIL state of a build (i.e. one or more benchmarks did not
   build correctly by constructing a file
     log/YYYYDDMM-HHMM/fail.txt
   (for the same time as in point (1) ).
Note: Either a pass.txt or a fail.txt file is constructed, not both.
