PATCH: tack: Allow echoing of compilation commands

[Samuel Bronson]

Description: Allow echoing of compilation commands
 Make the abbreviated "make" output optional, defaulting to off.
 .
 Can be turned on by passing the "--disable-echo" flag to configure,
 just like for ncurses (from which some of the code is copied).
