test_build_time.sh is a bash script intended to be used in conjunction
with "git bisect run" in order to find regressions in build time, however
it can also be used independently. It cleans out the build output
directories, runs a specified worker script (an example is
test_build_time_worker.sh) under TIME(1), logs the results, and returns
a value telling "git bisect run" whether the build time is good (under
the specified threshold) or bad (over it).

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.

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.

Python was missing a lot of debug information. Switch to use the default
-dbg package. Also add some additional debug information to the -dbg package.

bbvars.py will compare recipes in meta directories with documentation files
and report on variables that don't appear to be documented. It reports the
number of times a variable is used as well as any doctags present in the
documentation config file.
The output of this is intended to aid in determining where documentation may
be lacking, but it is not perfect, and does generate some false positives. An
experienced eye and careful attention to count and doctag should be applied to
the results.
$ ./bbvars.py -d ../../documentation/poky-ref-manual/poky-ref-manual.html -m ../../meta -t ../../meta/conf/documentation.conf -T | head -n 10
Found 1413 undocumented bb variables (out of 1578):
VARIABLE COUNT DOCTAG
===================================================
BUILD_ARCH 4 The name of the building architecture. E.g. i686.
BUILD_CC_ARCH 2 FIXME
BUILD_PREFIX 4 FIXME
BUILD_SYS 13 FIXME
BUILD_VENDOR 2 FIXME
CACHE 1 The directory holding the cache of the metadata.
COMPATIBLE_HOST 19 A regular expression which matches the HOST_SYS names supported by the package/file. Failure to match will cause the file to be skipped by the parser.
