It should be possible to insert argument as plain 'text' in config and inside class __construct($constant1) then request constant through variable by constant($constant1) function.

But I am not sure about global constants here, because they may not be defined at time of using, but it shouldn't be a problem for class constants with whole namespace, because namespace locator is already defined at moment of calling the class.

Example config:

services:
    my_service:
        class: Some\Class
    arguments:
        - 'My\Bundle\DependencyInjection\MyClass::MY_CONST'

and example class method:

public function __construct($arg1)
{
    $myRequiredConstantValue = constant($arg1);
}
