buildman: Show the build rate at the end
It is interesting to note the number of builds completed per second to track machine performance and build speed. Add a 'rate' value at the end of the build to show this. Signed-off-by: Simon Glass <sjg@chromium.org>

Build summary
|
||||||
|
=============
|
||||||
|
|
||||||
|
When buildman finishes it shows a summary, something like this:
|
||||||
|
|
||||||
|
Completed: 5 total built, duration 0:00:21, rate 0.24
|
||||||
|
|
||||||
|
This shows that a total of 5 builds were done across all selected boards, it
|
||||||
|
took 21 seconds and the builds happened at the rate of 0.24 per second. The
|
||||||
|
latter number depends on the speed of your machine and the efficiency of the
|
||||||
|
U-Boot build.
