I don't use kas.

I've ran `bitbake -e multiconfig:qemuarm-stretch:isar-image-base` and 
DISTRO/DISTRO_SUITE are expanded properly:

# $DISTRO [2 operations]
#   set /home/myo/work/isar/src/trunk/isar/build/conf/local.conf:30
#     [_defaultval] "debian-stretch"
#   set? 
/home/myo/work/isar/src/trunk/isar/meta-isar/conf/multiconfig/qemuarm-stretch.conf:6
#     "debian-stretch"
# pre-expansion value:
#   "debian-stretch"
DISTRO="debian-stretch"

...

#
# $DISTRO_SUITE
#   set? 
/home/myo/work/isar/src/trunk/isar/meta/classes/base-apt-helper.bbclass:5
#     "${@ d.getVar('DISTRO', True).split('-')[1]}"
DISTRO_SUITE="stretch"



If I set in local.conf

DISTRO ??= "debian-jessie"

DISTRO/DISTRO_SUITE are also expanded properly:

# $DISTRO [2 operations]
#   set /home/myo/work/isar/src/trunk/isar/build/conf/local.conf:30
#     [_defaultval] "debian-jessie"
#   set? 
/home/myo/work/isar/src/trunk/isar/meta-isar/conf/multiconfig/qemuarm-stretch.conf:6
#     "debian-stretch"
# pre-expansion value:
#   "debian-stretch"
DISTRO="debian-stretch"

...

#
# $DISTRO_SUITE
#   set? 
/home/myo/work/isar/src/trunk/isar/meta/classes/base-apt-helper.bbclass:5
#     "${@ d.getVar('DISTRO', True).split('-')[1]}"
DISTRO_SUITE="stretch"


Kind regards,
Maxim.
