build: colorize gcc only if on tty

Rather than forcing gcc to always produce colorized error messages
whether on tty or not, enable automatic colorization by ensuring
GCC_COLORS is set to a non-empty string.

Doing it this way removes the need for workarounds in ~/.emacs or
~/.vimrc for "M-x compile" or ":make", respectively, to work.
