If you need to bail from a calling makefile/bash script if an error 
occurs do this:

LOG=<your_log_file>

( <your_command> | tee -a ${LOG} && exit $PIPESTATUS ) # append to a log 
file

( <your_command> | tee ${LOG} && exit $PIPESTATUS ) # overwrite the log file

Then the calling makefile/bash script will bail on an error and not 
continue.
