[gentoo-dev] [PATCH 2/5] python-single-r1.eclass: Fix python_gen_* w/ single PYTHON_COMPAT impl

[Michał Górny]

Fix python_gen_useflags() and python_gen_cond_dep() to output correct
flag name when only a single implementation is listed in PYTHON_COMPAT.
In this case, the PYTHON_SINGLE_TARGET flags are not emitted
and PYTHON_TARGETS are used directly instead.
