[committed] Simplify --odr/--no-odr parsing

[Tom de Vries <tdevries@suse.de>]

Hi,

The --odr and --no-odr flags are currently setting odr_parsed and no_odr_parsed
variables, which in turn trigger setting the odr variable.

Simplify this by having the --odr and --no-odr flags set the odr variable
directly.

Committed to trunk.

Thanks,
- Tom

Simplify --odr/--no-odr parsing

2020-01-24  Tom de Vries  <tdevries@suse.de>

	(odr_parsed, no_odr_parsed): Remove variables.
	(dwz_options): Use odr variable in --odr and --no-odr entries.
	* dwz.c (main): Remove handling of odr_parsed and no_odr_parsed.
