The extensible SDK primarily consists of a pre-configured copy of
the OpenEmbedded build system from which it was produced.
Thus, the SDK's configuration is derived using that build system and
the following filters, which the OpenEmbedded build system applies
against <filename>local.conf</filename> and
<filename>auto.conf</filename> if they are present:
the filters shown in the following list.
When these filters are present, the OpenEmbedded build system applies
them against <filename>local.conf</filename> and
