Although I think the current embedded profile needs some love, I
noticed that /usr/portage/profiles/embedded/make.defaults has:

# Variables that are set exclusively by the profile
# and not by user configuration files.
PROFILE_ONLY_VARIABLES="ARCH ELIBC IUSE_IMPLICIT KERNEL USERLAND 
USE_EXPAND_IMPLICIT USE_EXPAND_UNPREFIXED USE_EXPAND_VALUES_ARCH 
USE_EXPAND_VALUES_ELIBC USE_EXPAND_VALUES_KERNEL 
USE_EXPAND_VALUES_USERLAND"

Removing ARCH from this list fixes the "ARCH is not set.." problem. This 
is
a quick fix we could do for now. I don't know if this has any negative
implications though.
