Unfortunately this is not enough; after updating
inc/Devel/CheckLib.pm, one test fails (silently and somewhere in the
(XS?) code itself):

   dh_auto_test

I tracked down the failure until
    my $m = magic_open( MAGIC_NONE() );
blib/lib/File/LibMagic.pm, sub _descr_handle, line 72,
but then none of magic was left.
