If we enable a component but a dependant library is disabled, then the enabled
component get silently disabled. Requesting all explicitly enabled components
allows configure to fail and show the missing dependencies instead of ignoring
our request.
For example if libdav1d is not availble ./configure --enable-decoder=libdav1d
succeeds but the libdav1d decoder will not be enabled. After the patch the
configure line will fail with the following message:
ERROR: libdav1d_decoder requested, but not all dependencies are satisfied:
libdav1d
