I was asking because the result after stripping would essentially equal
${sysconfdir_native}:

STAGING_ETCDIR_NATIVE = "${STAGING_DIR_NATIVE}${sysconfdir_native}"

It wouldn't work if someone set it to "${STAGING_DIR_NATIVE}/foo"
without adjusting sysconfdir_native, but on the other hand someone could
just as well use "/path-outside-staging-dir-native/etc", which would
break attempts to strip the prefix, too. I'd guess the assumption that
STAGING_ETCDIR_NATIVE doesn't get changed alone should be safe.
