Customized environment variables are not inherited to child processes created by the subprocess module. As a result the legacy board parser may not be able to locate the prerequisite utilities if they can be found only with the customized PATH. This patch passes the PATH of cli.py to the legacy parser so that both scripts use the same PATH to search for utilities. This patch is added in v2 of the series.
