dialyzer fails on OTP27 and OTP28

[sg2342]

after erlang/otp@196e7cd (which added specs to systools:make_relup/4) code in:

relx/src/rlx_relup.erl

Lines 41 to 50 in b228c36

	Options = [{outdir, OutDir},
	{path, [filename:join([OutputDir, "*", "lib", "*", "ebin"])]},
	{silent, true} | case WarningsAsErrors of
	true -> [warnings_as_errors];
	false -> []
	end],
	CurrentRel = strip_dot_rel(find_rel_file(Name, ToVsn, OutputDir)),
	UpFromRel = strip_dot_rel(find_rel_file(Name, UpFromVsn, OutputDir)),
	?log_debug("systools:make_relup(~p, ~p, ~p, ~p)", [CurrentRel, UpFromRel, UpFromRel, Options]),
	case systools:make_relup(CurrentRel, [UpFromRel], [UpFromRel], [no_warn_sasl | Options]) of

causes dialyzer failures because {silent, true} and no_warn_sasl in the 4th argument of the call to systools:make_relup/4 violates the spec:
