Using D without libphobos

I think you've got the technical answer already (just don't link 
in phobos2) but I'll add my 2c that Phobosless programming isn't 
just possible but realistically doable.  It's a shame to go 
without Phobos because it's got so much higher-level 
functionality, but if you're okay with writing things from the 
ground up in C-like code, it works.  Most third-party D libraries 
depend on Phobos, though, so it's mostly DIY and using bindings 
to other languages.

Have a look at the standard library here:
https://dlang.org/phobos/index.html

Basically, all the std.* is Phobos, and most of the core.* stuff 
needs linking with the D runtime library. However, there's a 
bunch of bindings to standard C stuff in core.stdc.* that only 
need the C runtime and standard library, and these come in really 
handy when you're not using Phobos.  (There are more 
platform-specific C bindings in core.sys.* that aren't listed on 
that page.)  Also, there are some other things in core.bitop and 
core.atomic (probably more) that don't need linking to druntime.
