# This means that an envionment variable named '<foo>_arm' overrides an
# environment variable '<foo>' (when ${TARGET_ARCH} is arm). And the same: an
# environment variable '<foo>_ramses' overrides both '<foo>' and '<foo>_arm
# when ${MACHINE} is 'ramses'. And finally '<foo>_local' overrides anything.
#
# This works for  functions as well, they are really just environment variables.
# Default OVERRIDES to make compilation fail fast in case of build system misconfiguration.
