if you are having difficulty with [1] then you could always have an
emulator running on real hardware, doing distcc.  you can set distcc to
do no compiling locally by excluding localhost. then you can have your
multi cores running happily within a virtualbox doing nothing more than
compiling for the limited arm device.  
on the virtualbox device, if you then ensure to have in
/etc/portage/make.conf
FEATURES="buildpkg"
then you get binary packages for free. this means that if something goes
wrong with the the device or you want to do this again on another device
you can use emerge -K (as long as you set the package location in
advance of course) and the hours of compiling become copy, untar, install
