[gentoo-python] [PATCH] Introduce DISTUTILS_COMMON_ARGS, for global scope.

["Michał Górny" <mgorny@gentoo.org>]

Just an idea to have a properly uppercase variable for options which
shall be set for all phases, rather than transitive mydistutilsargs.

Use cases: numpy, wxpython, most of the ebuilds using
DISTUTILS_GLOBAL_OPTIONS.
