That is exactly my usecase. I wan to build for all the machines with
exactly the same distro:

ricardo at neopili:~/curro/yocto/europa/build$ for a in
conf/multiconfig/*; do echo $a; cat $a; done
conf/multiconfig/inteli7.conf
MACHINE = "inteli7"
conf/multiconfig/qt5022.conf
MACHINE = "qt5022"
conf/multiconfig/qt5506.conf
MACHINE = "qt5506"

I am now trying to hack bitbake/lib/bb/cooker.py to convert all tasks
multiconfig:*:AAAAA-native into AAAAA-native
it might not be the final sollution, but maybe we can use it to
discuss further options.
