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?
