I'm writing a .bbappend for a recipe which contains a COMPATIBLE_MACHINE

to disturb what's there, just add my machine as well.
It's just a standard regular expression.
COMPATIBLE_MACHINE = "(machine1|machine2|machine3)"
COMPATIBLE_MACHINE .= "|machine4"
Will result in a value of "(machine1|machine2|machine3)|machine4",
which is still a perfectly valid pattern, as far as I can tell.
Yes, this does seem to work. Any clues why most uses of COMPATIBLE_MACHINE
use the regex "(x|y|z)" instead of just "x|y|z"? Aren't they the same?
