patch v1

Two improvements:
1. In silent mode, we hook in an ELOG because GNU make doesn't print the command that failed. Pymake does, so the hook just creates unnecessary shell processes.
2. REPORT_BUILD causes a shell invocation for every single file build, and it can simply be replaced with $(info) since it's always the first command in a recipe.

This seems to speed up builds by around 2 minutes (4-5%) on my computer.
