Add a BBFILE_PATTERN_IGNORE_EMPTY variable to allow ignoring the fact
that a regex specified in BBFILE_PATTERN for a particular collection
doesn't match any recipes. This will be used in OpenEmbedded in the
workspace layers created by "devtool" which may not always contain any
recipes (which is not cause for warning the user).
