[gentoo-dev] [PATCH 1/2] ninja-utils.eclass: Add NINJA_VERBOSE

[Matt Turner <mattst88@gentoo.org>]

ninja operates in one of three modes:
 - verbose (with -v): prints build commands
 - quiet (with --quiet): prints nothing
 - normal: prints [XX/YY]-style build status updates

samurai works the same way, except it does not have a quiet mode.

Thus we can't simply override ninja-utils' hard-coded flag from callers
of eninja.
