[OE-core] is standard for COMPATIBLE_MACHINE to use "()" or not?

[Robert P. J. Day]

  a style guide thing ... it appears that COMPATIBLE_MACHINE happily
acccepts a matching RE within parentheses or not, is there a
preference?

  also, in checking that, i ran across this in oe-core:

linux-yocto_3.14.bb:COMPATIBLE_MACHINE = "qemuarm|qemuarm64|qemux86|qemuppc|qemumips|qemumips64|qemux86-64"
linux-yocto_3.19.bb:COMPATIBLE_MACHINE = "qemuarm|qemuarm64|qemux86|qemuppc|qemumips|qemumips64|qemux86-64"
linux-yocto-dev.bb:COMPATIBLE_MACHINE = "(qemuarm|qemux86|qemuppc|qemumips|qemumips64|qemux86-64)"

where the first two recipes list "qemuarm64" but the dev version
doesn't ... is that deliberate?
