egg.mk and do-*

[Manuel Bouyer <bouyer%antioche.eu.org@localhost>]

Hello,
so, since xentools415 has been converted to python/egg.mk (from extention.mk)
we get a warning about do-build and do-install being redefined.
The do-build and do-install targets from python are being ignored, and indeed
xentools415 doesn't want to use them. The attached patch allows a client
package from python/egg.mk to choose to not use python's do-* targets,
by defining PYDISTUTILSPKG to no.

Is it OK to commit ?
