[PATCH] setuptools: Make options for setup.py more flexible

[Gary Thomas <gary@mlbassoc.com>]

[-- Attachment #1: Type: text/plain, Size: 551 bytes --]

The setuptools class uses hard-wired options for 'setup.py' during
the install step.  In particular, not all versions of setup.py
support the "--single-version-externally-managed" option.  This
patch allows for a recipe to easily override these options, while
leaving the majority (important) setup options intact.
