Darren Hart fa4bcfdb73 bb-matrix: correct BB and PM number canonicalization
The bash string operation ${BB##*0} was greedy and in addition to converting
"02" to "2", also converted "20" to "", causing all builds for a BB value ending
in 0 to run with BB_NUMBER_THREADS=1.

Darren Hart b8f6c225cd bb-matrix: initial scripts to record TIME(1) metrics for BB and PM combinations
The bb-matrix.sh script will run a bitbake command, building core-image-minimal
by default, for various combinations of BB_NUMBER_THREADS and PARALLEL_MAKE. It
records all relevant metrics of the TIME(1) command for each combination in a
data file.

The bb-matrix-plot.sh script can be used to visualize each of these metrics via
a 3d surface plot, either solid surface or wireframe with a value-map
projection on the XY plane.
