If we enable a component but a dependant library is disabled, then the
enabled
component gets silently disabled. Warning about disabled explicitly enabled
components
allows configure to show the missing dependencies and if --fatal-warnings is
used it can also fail if the user wants it so.

For example if libdav1d is not availble ./configure
--enable-decoder=libdav1d
succeeds but the libdav1d decoder is not be enabled. After the patch
configure
will warn about this:

WARNING: Disabled libdav1d_decoder because not all dependencies are
satisfied: libdav1d

The patch produces many warnings for:
$ ./configure --disable-everything --enable-decoder=mp*
Is this intended?

It reports only disabled decoders which start with mp, so it works as it should the way I see it.

Marton
