Bug 1403519 - only build docs when necessary r=gps This marks **/docs/** as exclusively docs, and code that is autodoc'd as inclusively docs. That means that a change that purely modifies documentation files will *only* run `docs` tasks, while a change that modifies autodoc'd source code will *additionaly* run `docs` tasks. The tasks do not run by default. MozReview-Commit-ID: G9tOK0AwtrI

#   $(ELOG) $(CC) $CFLAGS -o $@ $<
#
# This shell script is used by the build system to print out commands that fail
# to execute properly.  It is designed to make the "make -s" command more
# useful.
#
# Note that in the example we are sourcing rather than execing the script.
# Since make already started a shell for us, we might as well use it rather
# than starting a new one.

    echo
    echo "In the directory " `pwd`
    echo "The following command failed to execute properly:"
    echo "$@"
    exit 1;
