Subject: build system: allow monochrome 'make menuconfig'

'make menuconfig' uses a hardcoded colour palette which may be
difficult to read.  Add support for the 'COLORS' environment
variable.  Setting this to '0' will cause 'make menuconfig' to
be displayed in black and white.

(GitHub issue #273)
