you probably want to create a new profile dir:
        profiles/arch/powerpc/ppc64/little-endian/
then add a make.defaults file with the right CHOST defaults.  as we find
packages that have problems on little endian, that provides you a safe
space to mask features too.

then create a new target for linux users:
        profiles/default/linux/powerpc/ppc64/13.0/64bit-userland/little-endian/
that'll inherit the arch/powerpc/ppc64/little-endian parent

i said "ppc little endian", not "ppc64le".  historically speaking, ppc64le 
hasn't been a thing, and the only people doing ppc little endian are 32bit
embedded users.  that doesn't mean we can't make stages/iso for both.

ideally someone on the ppc side would pick you up, but i think they've been
a bit of a skeleton team of late.  so if need be, i can help you here.

you mean my bootstrap-portage script ?

do you have hardware ?  then it's simply a matter of booting Gentoo in it and 
filing/fixing bugs :).
