[OE-core] what means PROV_class-native = ""?

[Robert P. J. Day]

  perusing oe-core for examples to demonstrate the concept of
"PROVIDES =", and i ran across this in recipes-devtools/dpkg/dpkg.inc:

PROV = "virtual/update-alternatives"
PROV_class-native = ""

PROVIDES += "${PROV}"

  i'm not sure what to make of that -- what's the purpose of assigning
to PROV, then subsequently assigning to PROVIDES, but with that

PROV_class-native = ""

line in between?  i did a grep and saw nothing else like it throughout
oe-core.
