301 Before we test a flag against the whitelist, we append _${PN}
302 to it. We then try to match that string against the
303 whitelist. This covers the normal case, where we expect
304 LICENSE_FLAGS to be a simple string like 'commercial', which
305 the user typically matches exactly in the whitelist by
306 explicitly appending the package name e.g 'commercial_foo'.
307 If we fail the match however, we then split the flag across
308 '_' and append each fragment and test until we either match or
309 run out of fragments.
