hmm, looking at multilib.eclass, this part looks like it need extension:
# This is for the toolchain to setup profile variables when pulling in
# a crosscompiler (and thus they aren't set in the profile)
multilib_env() {
local CTARGET=${1:-${CTARGET}}
case ${CTARGET} in
...
powerpc64*)
export CFLAGS_ppc=${CFLAGS_ppc--m32}
export CHOST_ppc=${CTARGET/powerpc64/powerpc}
export CTARGET_ppc=${CHOST_ppc}
export LIBDIR_ppc="lib"
export CFLAGS_ppc64=${CFLAGS_ppc64--m64}
export CHOST_ppc64=${CTARGET}
export CTARGET_ppc64=${CHOST_ppc64}
export LIBDIR_ppc64="lib64"
: ${MULTILIB_ABIS=ppc64 ppc}
: ${DEFAULT_ABI=ppc64}
Anything more?
