Also in the build/target/product folder you will want to look at the *.mk files and make some edits to remove packages you do not want. You will have some stuff like the following
Telecom \
TeleService \
MmsService \
TelephonyProvider \
most of these can be found in core_base.mk, generic_no_telephone.mk and core.mk. But look them all over, they have pointers starting with full_base.mk and will link you to each file there after.
Good Luck!
