Description Raúl Porcel (RETIRED) gentoo-dev 2011-11-20 19:13:36 UTC 
The toolchain.eclass does:
if [[ ${PN} != "kgcc64" && ${PN} != gcc-* ]] ; then
    IUSE+=" altivec cxx fortran nocxx"

therefore sys-devel/kgcc64 doesn't have cxx or nocxx as IUSE.

Then there's this sanity check in the eclass:
    # Sanity check for USE=nocxx -> USE=cxx migration
    if (use cxx && use nocxx) || (use !cxx && use !nocxx) ; then
        eerror "We are migrating USE=nocxx to USE=cxx, but your USE settings do not make"
        eerror "sense.  Please make sure these two flags line up logically in your setup."
        die "USE='cxx nocxx' and USE='-cxx -nocxx' make no sense"
    fi

Which will die on sys-devel/kgcc64
