Summary0000530: Date stamping recalculated for each file.
DescriptionThis should be done once, so the structure of the makefile is a little broken. It doesn't have any practical impact, besides build speed, though, because only one file holds that information anyway. It would be nicer if it was calculated at the start of the make process and used as-is after that.

Since only one file needs to defines for the date stamp, build os, and such, adjust the Makefile(s) to only define those for that ONE FILE. This also makes it easy to set an env var or similar to turn them to a fixed string for being able to check the firmware md5sum, which would always be different due to the timestamp and other dynamic info interjected in the file.
