games-simulation/EmptyEpsilon: drop bogus GCC check

The ebuild doesn't depend on media-libs/libsfml but also, that error
generally appears when something C++ was built against newer GCC and
then you're trying to link against it using older GCC (=> older libstdc++).

Besides, <11 is masked and has been for a while.
