# A variable '<foo>_qemuarm' overrides '<foo>' and overrides '<foo>_arm' when ${MACHINE} is 'qemuarm'.
# If you use combination ie '<foo>_qemuarm_arm', then '<foo>_qemuarm_arm' will override
# '<foo>_qemuarm' and then '<foo>' will be overriden with that value from '<foo>_qemuarm'.
# And finally '<foo>_forcevariable' overrides any standard variable, with the highest priority.
# This works for functions as well, they are really just variables.
