Understand why kernel modules became so large after v3.0 #78
Description
As of 2d360b0 the release zip has become very large at about 160MiB compared to v3.0 60MiB.
Part of this is due to the addition of baremetal binaries.
However, the buildroot image also got way larger. There isn't a single file that dominates it, but the bulk is clearly under /lkmc.
One thing that looks the most suspicious is that kernel modules have become like 5x larger, we should understand what has led to this change.
