Determine the default compiler to use for this instance
The default compiler will be used unless --compiler is specified.
The environment variable DC will take precedence over anything,
followed by the configuration. If nothing is found, the folder in
which dub is installed will be searched, and if nothing is found,
the $PATH will be searched.
In the majority of cases, as we distribute dub alongside the compiler,
it will be found once the directory in which dub reside is searched.
