It sounds like you want to simply link against druntime and not phobos.

In many cases, phobos and druntime are bundled together as a static 
library. If you just want druntime (core and rt) then you probably have 
to build druntime from source.

I'm generally working on dmd, so I don't know how it works for ldc. But 
I'm sure it's quite similar (building druntime with dmd is just one make 
command).
