log your make commands!

• record exact command with options
• prepend every line of output with a timestamp
• prepend STDOUT lines with OUT
• prepend STDERR lines with ERR
• append all output to make.log in the working dir and display on screen

usage:

Add the lmake function to your .bashrc and do source ~/.bashrc
To run, simply replace make with lmake in your command as in $ lmake <make options here> <optional make target>

$ lmake -k -j 4
