It would be somewhat useful if there where a way to annotate in recipes
what binary to check for on the host, so just doing
ASSUME_PROVIDED=sed-native would look up in the sed recipe to check that
"sed" exists on the host, so that SANITY_REQUIRED_UTILITIES doesn't need to
be maintained separately.

Very low hanging fruit though.  Patches welcome!
