Oddly enough I don't see this same behaviour when building, for example, core-image-minimal, so I have no idea what makes chromium so special and, therefore, whether other recipes might be similarly affected. Also, it seems as though a lot of the added time is coming from the linking stage, but I don't have (or know how to get) hard numbers for that. Is there a way to get build times for each task within one recipe? I've repeated this test 6 times (build just before binutils-2.26, build just after binutils-2.26) and the results are always within a couple minutes of each other. So I doubt this is some random occurrence.
