the rough part is mostly making so portage knows the paths and have the
bind-mount game working, the alternative way is to build the native part
by unpacking the cross packages and the build system packages there
so
/ <- emulated
/etc/ld.so.conf.d/native
/usr/${nativehost}/
/usr/${emulatedhost}/
and then you need to trick portage a bit
Sounds gory already? =)
