That's not how it's supposed to be done.  If, and that's an if, a
separate format for AMV is appropriate, it should be registered
conditional to CONFIG_AMV_DEMUXER.  Adding a dependency on the AVI
demuxer in configure will take care of only enabling it when AVI
is enabled.  This was a user can choose to disable only the AMV
demuxer with --disable-demuxer should he wish.
