ah, gotcha ... so in cases like that, even if a recipe needs to be
*partially* built for libraries, that in no way affects the
ASSUME_PROVIDED setting, correct? as in, once I ASSUME_PROVIDED
"bzip2-native", then that *better* exist on my build host, correct?

P.S. there is still some lack of sync amongst:
* ASSUME_PROVIDED
* sanity.bbclass
* YP quick start guide
one example i mentioned is that the YP guide does not list "sed" as a
build host requirement, but "sed-native" is in ASSUME_PROVIDED;
however, it's not listed in SANITY_REQUIRED_UTILITIES. that seems
inconsistent.
