distutils-r1.eclass: Introduce DISTUTILS_USE_PEP517=no mode Introduce a new DISTUTILS_USE_PEP517 value "no" that stands for "no build system". This is primarily meant to replace the legacy distutils-r1 logic used for bootstrapping baseline PEP 517 packages. At the same time, it provides a convenient replacement for some of the uses of python-r1. In this mode, the eclass does not add PEP 517-specific dependencies and the default python_compile() is a no-op. However, it does set dependencies, REQUIRED_USE and enables sub-phase usage (with respect to DISTUTILS_OPTIONAL). It also permits using distutils_enable_{sphinx,tests}.
