Here are the results for build time changes (with -j1) per-benchmark for spec2k/2k6. The build times for spec2k were much more stable then the ones for spec2k6. The build time improvements are probably false positives.

\* The build workload is too small for the results to be significant. The best thing to do is to ignore these results.
I think this shows that this change doesn't significantly impact build times.
