and test app?
- or I must write some batch or Makefile and call `dmd` compiler 
directly onto every file?
- what `dmd`/`dub` command line options forces it to drop 
system-wide druntime/phobos and use custom local .so / .a library 
in place of it?

Yes, my engine does that

If you have a module source file with the same name you want to 
replace, the build will prioritize your own version.

You mean I can create `project/druntime`, and replace the core D 
runtime part by part by placing here my own files from druntime 
source?

And compiler will route his internal callbacks etc into my own 
partial stdlib without any undocumented options or .a/.so 
prebuilding ?
