[gentoo-dev] [PATCH] python-utils-r1.eclass: support PYTHON_IMPLS_NO_STRICT variable

[Zac Medico]

This is intended to be set by the user when using ebuilds that may
have unknown implementations in PYTHON_COMPAT. The assumption is
that the ebuilds are intended to be used within multiple contexts
which can involve revisions of this eclass that support different
python implementations.
