Shell functions in bitbake are executed with /bin/sh so should be POSIX
compliant and not use Bash extensions, or at least only use extensions that are
implemented in both dash and ash (busybox).
This tool will extract all of the shell scripts from all recipes and run them
through checkbashisms (it assumes that checkbashisms is on $PATH).
There is a whitelist to filter out false-positives such as the use of $HOSTNAME
(a bashism) in functions where we have defined it, or using the 'type' builtin
which is supported by ash/dash.
