Most of the time, bash will not replace variables inside single quotes,
so I am not sure that would work.  I use for my mock script:

mock --configdir=$configdir -D "dist $dist" -r $mock_cfg <other options>

It seems not to get confused with double quotes there .. but it puts in
the literal value $dist if I use single quotes.
