[gentoo-dev] [PATCH 1/2] python-utils-r1.eclass: Fix PYTHON_LIBS for py3.8+

[Michał Górny]

Python 3.8+ provides two pkg-config files: python-3.8 for building
Python extensions and python-3.8-embed for embedding Python in other
programs.  The former no longer lists -lpython*, resulting in empty
PYTHON_LIBS.  Since our consumers are more likely to want it non-empty
if they already query it, switch to the latter file.
