The reason for doing a script is to allow building multiple stuff
when I am sleeping or travelling, and as long as things complete
I do not mind the 10 minute pauses.

When I am working interactively, I do not want to specify MACHINE
everytime I do something

Maybe this is something that would work...
alias bitbake="MACHINE=${BB_MACHINE} /path/to/bitbake"
