[gentoo-dev] [PATCH eutils] Die if epunt_cxx is called unnecessarily.

[Michał Górny]

Currently, epunt_cxx always succeeds. This results in some
of the ebuilds keeping its use even though the C++ checks were removed
upstream.

Therefore, I'm suggesting to add a simple check to the function -- if
none of the patching attempts succeed, die requesting the user to remove
the invocation.
