[gentoo-dev] games.eclass: handle verbose build log for egamesconf in EAPI<5

[hasufell]

already filed a bug, but no response so far
https://bugs.gentoo.org/show_bug.cgi?id=444478

any comments?

This is sane imo, cause some games herd developers don't agree with the
"always latest EAPI" thing which is no official policy anyway.
