Add a bunch of generally used command macros:

    BZCAT, BZIP2_CMD, CHGRP, CUT, DC, ECHO_CMD, EGREP, FILE, FIND,
    HEAD, ID, IDENT, STRIP_CMD, SU, TAIL, TEST, XARGS

And use shell (ash or ksh) builtins where available for efficiency:

    ECHO_CMD, FALSE, TEST, TRUE

Grepping the ports tree, a few dozen ports already have FIND,
STRIP_CMD and XARGS variables on their own and numerous ports use
these commands without using macros.  Some ports use FILE as a .for
loop variable, but it doesn't matter anyway.

Remove the definition of ECHO because it is already defined in
/usr/share/mk/sys.mk and leaving the useless definition may mislead
developers.  Add the following comment that would help:

    # ECHO is defined in /usr/share/mk/sys.mk and its value can either be
    # "echo", or "true" if the make flag -s is given.  Use ECHO_CMD where
    # you mean the echo command.
