Native and nativesdk flavors don't have packages, so RDEPENDS only works
when depending on ${PN}-native (but not for ${PN}-native-some-package). 

Try:

DEPENDS = "boost"
RDEPENDS_${PN}_class-target = "boost-program-options"

"boost" already is a dependency via DEPENDS, so you shouldn't need an
RDEPENDS for it in the native case.
